Bills Offensive Evaluation: Seantrel Henderson


Seantrel Henderson fell in the 2014 draft because of possible maturity issues. He came in and started every game for then coordinator Nathaniel Hackett. He was seen as a possible steal in the draft, because he has the size and skills of a first round tackle according to Mike Mayock. “If you want to draw up a first-round offensive tackle, this is the kid.” -Mike Mayock

Henderson is 6’7″, 331 pounds, has the length you want at the tackle position with a 34 5/8″ reach and huge hands measuring in at 10 1/2″ hands. The guy is an absolute specimen, he possesses the physical measureables that you want at left tackle let alone right tackle.



Henderson is still a young player in his first contract so his cap number isn’t that big. With the Bills looking to lock up Cordy Glenn, having a modest contract at the right tackle position is a plus. But the Bills need Henderson to produce. In order to produce we need the big guy on the field.

Henderson started every game in his rookie year. At times he struggled with his pass blocking. According to Pro Football Focus (PFF) he surrendered 6 QB sacks, 12 QB hits and 28 QB hurries. That was the 7th most total pressures given up by a tackle in the NFL. Well, 2015 was no different. To start, Henderson only played in 10 games this past season. In the second week of December Henderson was diagnosed with Crohns disease and after the game versus the Chiefs he missed the rest of the season. “He has experienced severe stomach pain and has lost nearly 20 pounds, according to the source.”

According Carucci’s source he lost 20 pounds and he was listed on the injury report with an “illness”. Players have played in the league with that bowel disease, but for a guy his size keeping on the weight may present a problem.

But his play in 2015 was on par with what he produced in 2014, Henderson seemed to struggle versus the pass.

According to PFF.

According to PFF.

His 95.1 pass blocking efficiency percentage is tied for 17th overall, and just a point higher than 2014 (based on tackles playing 25% of the snaps). His struggles blocking led him to commit 7 penalties which was the second most on the team behind Jerry Hughes. Three of those penalties were offensive holding calls, one ineligible man down-field, one false start, an illegal use of the hands, one illegal formation and one false start (

There was a slight improvement in his run blocking according to PFF.

According to PFF.

According to PFF.

I know it may not seem like it given his 37.9 run blocking grade, but based on the raw grading data that PFF utilizes to get that final grade, he finished better this year than in 2014. His statistical grading looks rough, but he is a young player who was really raw entering the league in 2014. So you have to expect some growing pains. But there still are question marks if he can even play in 2016, so the Bills will probably look to bring in a few players via the draft and free agency.



After watching several games of Henderson, I think some of the statistics may paint him to be worse than he really is. Henderson is a right tackle that does have his ups and downs. I would say his biggest asset are his long arms.

Smooth kick-slide, attacks to meet the rusher, his long arms neutralize the rusher.


If the defender isn’t rushing from a wide technique, more times than not he will be able to lock on.


Here are some more clips of how Seantrel’s long arms help him push rushers wide or allow him to lock onto defenders from a distance.


But in the NFL pass rushers get paid too. Defenders have counters to an offensive lineman’s skills. Although Seantrel has really long arms, when he was matched up against a rusher with a good swim or swipe move he struggled.

It is no surprise that when Kansas City shifted Hali to Henderson’s side, he struggled. Seantrel gets caught leaning and Hali swipes past the lineman for a strip sack. A huge turning point in that game.


Henderson gets beat again, but Tyrod bails him out. Taylor releases the quick deep pass to Watkins.


When the Bills played the Titans, Henderson was matched up versus a very talented, long pass rusher in Derrick Morgan. Morgan had a field day. Look at how Henderson tries using his long arms to neutralize Morgan, Morgan just swats his hands down en route to Tyrod.


On the following play Henderson’s feet stop moving and he is forced to hold Morgan. Seantrel struggled that day.


Henderson tends to rely on his physical traits too often, but it is easy to see why. His long arms really mask a lot of deficiencies in technique and foot-work. In tight space he is able to use that length to control and turn defenders. Henderson doesn’t have the quickest feet among NFL lineman. At times, his foot-work is sloppy and slow but he can sometimes overcome it.

Wake beats him inside off the snap, but his reach allows him to wall off the talented defender.


On the following play Henderson uses his right hand to post and seal the edge.


Versus the Patriots, Henderson demonstrated the ability to reach the 4i technique and hold the point of attack really well.


There is no doubt that he can block down and wall defenders when the Bills want to run power to his side.


Another great job here as Shady runs off tackle on the counter trey.


Many fans believe the Bills should select a tackle very early in this years draft, and I would agree if he is the best player available. As bad as the advanced statistics may be for Henderson, the film shows that he can be a starting tackle in the league. His weaknesses: footwork, strength and knee bend are things that are fixable. The Bills starting right tackle has the size, length and kick-slide that you want in this pass happy league.

Having a good offensive line coach in Aaron Kromer for the whole off-season is a blessing. Kromer is a really good motivator and teacher. He will be able to drill the techniques over and over again. But when it is all said and done, how good of a tackle Henderson will be is up to him. Will he be able to play with Crohns disease? Will his weight drop too low to maintain the strength and power that is needed on the pin and pull runs that Roman loves to call? Considering the issues he has dealt with; having Miller in and out of the lineup and the health issues, I think the jury is still out on how good of a player Henderson is. If healthy in 2016, I believe he has what it takes to be a starting right tackle over the next few years.
