I believe it is pretty clear that Josh Rosen is the most NFL ready QB in this class. He is mentally ready day one and has shown that he can play in multiple offenses over the course of his career. His football intelligence is unrivaled and will need to be challenged daily at the next level. Defenses will also need to challenge Rosen, as he recognizes routine coverages and knows what route combinations to attack with. Post-snap, he routinely worked through his progressions, typically making it to the 3rd or 4th option in his progression and makes decisions at NFL play speeds. Turning his back to the defense regularly on play action passes does not affect his post-snap recognition, which is a testament to his mental processing. He has shown the ability to throw to all areas of the field with anticipation and with very good accuracy. Throwing to a spot and throwing guys open within the structure of the play occur regularly. He not only understands the weaknesses in zone coverages, but he also understands the leverage weakness versus man coverage.

The scheme at UCLA last season called for aggressive pass sets by interior offensive linemen in order to give Rosen a nice, deep pocket and platform to throw from. So getting him off the ‘spot’ is a common strategy by defensive play callers. At times when the pass protection struggled or he was pressured, he was unable to improvise or ad lib. His throwing on the run or off platform leaves a lot to be desired, and it can all be traced back to his athleticism. His athleticism is average, and you can see that in his pocket movement and when he wants to extend plays outside of the pocket. In the pocket, he is able to climb, but his timing and rhythm are thrown off when asked to slide laterally. When it comes time to scramble, he doesn’t naturally feel the escape points, will get that ‘deer in the headlights’ look, then take a sack on the fringe of the pocket or make an awkward and inaccurate throw on the run.

Overall, Rosen graded out to a 5.416, which is a 1st round grade. Rosen’s best fit will be in an offense that gives the quarterback entire command of the playbook, one that stresses quick reads and throws into the short and intermediate area. He’s best suited to an offense that has a strong interior offensive line and utilizes plenty of play action to slow down opposing pass rushes. This will give him a clean pocket and platform for him to make all of the throws.

For more detailed notes and breakdowns, check out all of his film below.

UCLA vs. Stanford

3rd down and 3: No one open, but he keeps the drive alive because he always knows where his check-downs or outlets are.


You can see Rosen (EZ angle) telling his receiver what route he is supposed to run. The receivers run a little rub concept on 4th down, but the pass is a little hot. Receiver has to catch it.


2nd-and-8: Rosen shows poise in this backed up situation. Scans the field, doesn’t get fooled by DB Meeks (#24) who is in zone, but closes on the tight end. Rosen knows exactly where to drive this ball: low and away from Meeks. Dropped and intercepted.


Rosen notices the depth of the boundary safety and that the slight play action fake will hold him, so he uses his eyes to do just that, which allows the WR to get behind him and across the middle for a big gain.


We expect QBs to nail these kinds of throws in their sleep. The placement on WR screens is critical, but so is how quickly it gets there. Nice, accurate throw from the far hash.


3rd down: Rosen recognizes the defensive structure and changes the pass protection prior to the snap by keeping the TE in to block. He attacks the combo coverage to the field with a pivot route back inside, but the receiver drops it.


Not sure why Rosen didn’t pull the trigger here. His feet were in position to let it rip; instead, he holds the ball and DT Phillips gets the strip sack.


UCLA always manages to get Rosen deep pockets with play action passes or vertical sets by their tackles. It keeps pressure out of his face and away from his feet, which is great because he isn’t as mobile as a lot of other QBs. But what he can do is turn his back to the defense, work through progressions, and stick throws like this.


Stanford brings the corner blitz and Rosen is so zoned in on checking the safety rotations that he doesn’t realize that said blitz is coming. The WR recognized it, ran a hot route, but Rosen caught on too late. He also appears to prepare for the hit by fading away rather than sticking the throw. Something to keep an eye on as we move forward. The ball goes incomplete.


The Bruins utilized a lot of play action and aggressive interior offensive play to give Rosen clean platforms and deep pockets to throw from.


Rosen doesn’t have to worry about the safety this time. They bring the blitz and the WR just has to beat the CB. This is too easy for Rosen.


This is just incredible recognition by Rosen. The offense has an all verticals concept; on the snap, the field slot defender blitzes and the linebackers have to rotate. This means that the linebackers are opening to the field and gaining depth. Rosen wants to attack the Cover 2 defense with the bender route run by the tight end. The boundary safety sees it and tries to squeeze it, since the linebacker doesn’t even see the route developing. But that takes him out of the play as Rosen finds the #1 wide receiver in the end zone after being released by the corner.


Talk about throwing a guy open. Another all verticals concept, and Rosen throws it to a spot for his tight end.


UCLA vs. Colorado

What more can you ask for from your quarterback? Third-and-long, Rosen quickly scans the field but knows that the alley defender will widen after disrupting the route by the #2 WR. He anticipates the throw and sticks it perfectly for the 1st down.


Rosen appears to be reading low-to-high, so he may have missed a bigger play down the seam. But what is more important is the velocity on the throw and the decisiveness. His placement was high, but the fact that he was decisive and put some zip on it allowed him to complete it.


He escapes the pocket but is unable to complete the pass while on the run to his right.


Another throw that he makes looks easy. The WR isn’t open; in fact, he is being held, but Rosen has total control of the ball speed here. Throws to a spot, with a little something off of it so that the receiver can work back to it, and from the far hash, no less. Very nice.


Another 3rd-and-long situation. Rosen remains poised in the pocket, which is needed on this slow-developing ‘Dagger’ concept. He anticipates the speed dig route and is able not only to convert the 1st down, but also to turn it into an explosive play.


As the Bruins motion, the coverage changes and it looks like the defenders blow the coverage. The corner follows the #1 WR and the safety drops down to take the #2 receiver, but no one accounts for the #3 receiver. Once that corner gets into the hip pocket of the WR and the two defenders jump the flats, Rosen knows he has a touchdown. Great throw over the defense from the far hash.


Not the most mobile, but he does have enough to slightly extend plays. Nice move on the defender here, but the WR drops it.


Trick play call here, but look at how quickly he sets and throws this deep pass, AND the location is spot on!


He is so good off of play action. The Bruins run a flood concept and Rosen is quick in his drop, snaps his head around and delivers a very good pass.


A major barometer for a quarterback’s mental processing is his ability to read the coverage pre- to post-snap while in an empty set. Rosen shows why he is the most developed quarterback from the shoulders up on this play. The three WRs to the field aren’t open, so he quickly moves on and makes the throw in approximately 2.05 seconds.


At times, Rosen will stare down his targets into the boundary. He has the arm strength to overcome late reads when looking into the boundary, but not on deep passes. Not for the lack of arm strength, but just because of the speed and space that defenders can cover in that area. He stares this down too long and the safety makes a play.


He is almost automatic on play action passes over the middle. He confidently rifles this pass though the window.


Pressure is immediately in his face, so he fades away a little bit, but he ultimately completes it. This was one of the rare passes where he threw off platform.


This is just incredible. Rosen anticipates the dig and is completely aware of both safeties, especially the one that the receiver will encounter if led over the middle. So he back shoulders the throw low, with velocity to help the receiver evade a big hit or an interception by the defense.



UCLA vs. Arizona

One of Rosen’s favorite concepts is this snag/spot concept. So far, he has only thrown it to the corner and the spot route. On this play he thinks the linebacker is screaming to the spot route, so he holds it a tad too long, but he makes up for it with a shoulder fake that causes the linebacker to sit and get into the passing lane of the corner. So now Rosen has the clear window to make the throw.


Lucky for us, on the very next play they run it again and the flats defender doesn’t scream to the flats, so Rosen immediately throws it to the primary receiver in the flats for a short gain. He has mastered this concept.


Rosen is one of the few quarterbacks who doesn’t get stuck on a receiver in his progression and can actually move through his progressions quickly. The linebacker drops into the passing lane, so Rosen moves on to his next option.


Rosen let this one get away from him.


His internal clock is tuned well. The mesh concept isn’t open soon enough, so he hits his check down. An underrated part of his game is always knowing where his outlet is, even if he isn’t looking in that direction.


A rare play where he is unable to stand on the spot cleanly. His primary receiver is taken away over the middle and he’s not able to slide to find a clean platform to throw from. He tries throwing off platform by elevating like it’s a jump shot, but it goes awry.


Finally, some adversity! On UCLA’s next drive they call a couple of runs and then have Rosen make a throw off of play action. The throw from the far hash sails a bit and the defensive back takes it to the house.


Still the same drive, and Rosen does a great job of using his eyes to hold the boundary corner but he overthrows it.


Arizona disguises their defense really well on 3rd-and-long, and it creates some pressure. Rosen steps up and you will notice his knees and center of gravity are a little too low. This means when he wants to release it he is going to have to elevate, which can create accuracy issues because it throws off the the quarterback’s balance and throwing process.


Rosen took a sack on the prior play and suffered a big hit to the head. You could tell the hits, pressure, and overall game that Arizona put together sort of got underneath Rosen’s skin, as his mechanics began to deteriorate. On this play, as he waits for the routes to develop he has guys in his face and his base becomes to wide. He is, again, sitting too low and must elevate in order to throw, but his wide base doesn’t allow him to put velocity on it.


The offense got a few good runs to get into position to score a TD and Rosen capitalizes.


Rosen had trouble distinguishing who the fourth rusher was going to be in this game. He took several sacks, but he is just simply unable to make a guy miss and escape the pocket. He will be on the fringe of escaping the pocket, but then will get taken down by a shoestring tackle. He doesn’t have a fight or flight response; he becomes a deer in headlights.


Rosen gets stuck on half of the field, sees ghosts, and tries to escape when a receiver is coming open.


His decision making and confidence in his throws was definitely down in this game. Arizona plays a cover 3 defense and the linebacker picks it off to end the game.


UCLA vs. Oregon

UCLA uses a lot of play action, and Rosen is so good at getting his head around to his keys and into this progressions. But there isn’t a QB in this class that is better at utilizing his tight end. Usually it’s a Y-stick, but this time it’s an intermediate crossing route that Rosen nails. The placement is huge because it keeps the tight end safe as the safety is lurking.


Rosen is looking deep here, but he throws it a little too flat. I think if he releases it when he intended which was during the double clutch, he has the velocity and trajectory to complete it. Instead, he reloads and the ball comes out too flat, and it gives the DB a chance to make a play on the ball.


This is a one read and throw type of pass, and Rosen does a great job of doing the little things to execute it. The play action fake is called off by the running back because of the edge pressure, but Rosen uses his eyes to hold the deep safety. He also does a great job of not cueing the defense with his body language. By that I mean his feet and shoulders aren’t even pointed completely at his target, but he is able to nail the back shoulder throw with touch.


This is a quick slant to Rosen’s left, but it is covered, so he works through his progressions to the third receiver. Knowing quick set pass blocking is going to break down and his receiver is not open, he extends the play IN the pocket with a slight shoulder fake to get the linebacker to move just a bit. It helps uncover the receiver, and he makes a good catch as the ball is placed a little high.


You often hear people say that Rosen isn’t that athletic, and this is what they mean. When he needs to maneuver the pocket it appears very clunky and robotic. He doesn’t have very good weight distribution when he does move, and it affects his mechanics. It leads to control issues on this play. The ball hangs because he isn’t able to transfer his weight smoothly and get into his normal delivery process.


So we see that when he needs to drive it outside from the far hash, he struggles. In the Arizona game it was a deep comeback to his left; this game, it’s an intermediate comeback to his right. The WR catches it, but pay attention to the placement and velocity.


Rosen does a great job of rolling to his left, finding a window where he can get enough time to get his hips around in order to get this throw off. I am not sure he nails this without that.



UCLA vs. Washington

Not sure if this was typical of Washington, but they bring the blitz and Rosen doesn’t run the ball; he throws it to the sight adjustment. The decision is obviously determined prior to the snap.


Rosen wasn’t seeing the field well. Even though the offensive line wasn’t doing him any favors early in this game, he didn’t respond well to the pressure. On this play, Washington runs a stunt and the looper shows; Rosen looks to escape instead of just throwing the flare.


This is his worst play of the season, in my opinion. The Huskies rush two and spy Rosen, and he sees ghosts and attempts to leave the pocket with receivers open. But the route concepts were questionable at best.


Considering how the first quarter went and how shaky he looked, he does a good job of hanging in the pocket on this play. When he attempts to move in the pocket, his movement and shifting of his weight is clunky.

This is a play action pass on which Rosen has to fake it to the running back but then quickly get his head all the way around. Seems easy, but his rotation is so quick, and it helps him analyze the field.


The Huskies had the offense’s number. They were able to get into Rosen’s head early, but then they knew how to attack the offense – loopers attacking the middle of the offensive line and rushing LBs to get 1-on-1s vs. the running backs. Point is, get Rosen off the spot. He has an opportunity outside the structure of the play to make a throw to a wide open tight end down the seam, but he doesn’t pull the trigger. He does show off his athleticism by escaping and throwing it away.


A little trickeration in the red zone, but the location on this throw is still insanely good. No chance any other person is catching that.


Take a look at Rosen as he executes the play fake. He peeks to the backside, knowing that the rusher was coming and the back was going to pick him up. The defender gets his hand on him and he is forced to throw it off platform, though he does get it to the WR. Placement is slightly off, but that is typical when his feet aren’t set.


Watching him throw on the run is tough at times, especially when he goes to his left.


His processing speed was bad in this game; typically, he works through three progressions no problem. He needs to hit the check down here to the running back, or to just throw it away.


Third down and four, Rosen has to drive it outside to his left. It’s very good coverage vs. an in route, and Rosen is completely off target.


This was Rosen’s last throw of the game, and it was fitting. His processor, internal clock, and play speed altogether were off, and it showed again on this play. He has the drag route but fails to throw it and takes a big hit. He finished this game 12/21 for 93 yards and 1 touchdown.


UCLA vs. Arizona State

The pass isn’t complete, but I am going to give him a pat on the back for his recognition of the coverage. Post-snap you can see the field corner open his hips and read the route of the #2. This is a version of quarters coverage, and Rosen realizes that immediately. Just look at the body posture compared to the boundary safety. Once the #2 receiver runs the out route, the corner can trap or jump it, which means the safety has to roll over the top to cover #1. That safety is flatfooted and late, but Rosen and his teammate were unable to connect.


On 3rd-and-5, there is no reason Rosen shouldn’t give his WR a shot on this double move. The edge defender flashes in his line of vision and he decides to pull it down and throw it away.


On this play Rosen goes through the progressions, and you can see how his feet are always tied to them and his targets. Good anticipation, but the placement is off and the ball is dropped.


Rosen shows off his arm strength on this play action pass. While we shouldn’t question his overall arm strength, especially when you see plays like this, the velocity needed for this touch throw isn’t the best measurement of arm strength. In other words, he didn’t need to drive this or throw this on a line, it was more of a touch pass.


More evidence that he can work through his progressions. This throw to his tight end is his fourth option on the play. He quickly checks the wheel route, the post route, the shallow cross, and then slightly climbs the pocket extending the play and hitting the tight end. But he drops it.


I may sound like a broken record, but he does it again. This receiver is his fourth option. He scanned the entire field while dropping. Not much more evidence is needed to convince me that he isn’t the consensus #1 QB at this moment.


While I still believe he struggles with pressure and escaping defenders when pressured, he does a great job of breaking the tackle here and knowing where his back is as an outlet.


He gave ASU defenders headaches this game. He somehow makes the defender miss and gets it to his teammate in the flats.


This is a well designed play and Rosen had a touchdown either way you look at it. But watch his poise as the pocket is being pushed in his face. Yet, he keeps his eyes downfield and delivers a strike that is low but doesn’t break the stride of the receiver.




UCLA vs. Hawaii and Memphis
