Barnett's first step isn't the most explosive one you'll find, but he more than makes up for it at times because of how well he studies his opponents and keys into their snap counts. That allowed Barnett to consistently win "high side" or outside the offensive tackle, and one of his favorite outside moves was the chop.

Here's a great example of Barnett's chop move, where he violently knocks the blocker's hands down before they can lay a finger on him. He times that move perfectly, allowing him to blow by the right tackle on his way to a sack against Kentucky. Every Eagles fan has probably heard by this point that Barrett broke the immortal Reggie White's career sack record with the Volunteers. What I love about that number, as Cole Cubelic from the SEC Network pointed out last fall, was that a large majority of his sacks came against conference foes. That is something not every top pick can say. Instead of picking up large bunches of sacks against, say, Texas-San Antonio, Tennessee-Chattanooga, and Nevada, Barnett was credited with a sack in every conference game this past season.

I recently went back and watched him in his true freshman season in 2014 against Ole Miss, where he racked up three sacks while spending a majority of his time lined up against Laremy Tunsil, who was considered by most to be one of the top three prospects in the 2015 NFL Draft. Tunsil got the best of Barnett on a few snaps, to be sure, but Barnett routinely made high-effort plays in all phases of the game, got numerous hits on the quarterback, split double teams, and overall had a strong outing on the road against a nationally ranked Rebels team. That was a really impressive game to watch, and in that game I saw a couple of examples of something that consistently popped up with Barnett when watching him throughout his career.

When you're a talented pass rusher, teams are going to get creative with how to block you. If they have a stud tackle like Tunsil, you may see a good amount of straight one-on-one attempts, but sometimes you'll get the protection slid in your direction. Sometimes, however, the protection may slide away from you, leaving you with a tight end and a running back chipping you out of the backfield. This is no easy task when you're trying to get after the quarterback, especially as a young pass rusher, but Barnett showed at a young age that he could make plays like this against Ole Miss. I also saw it numerous times last year as well.

Here against Georgia, the offensive line slides the protection away from Barnett, only to have him matched up against two blockers (a tight end and a running back). Barnett fights through the traffic, maintains his vision on the quarterback, and brings him down for a sack, a forced fumble, and a defensive touchdown.

Here are a few more shots that you need to see if you watch anything of Barnett. Whether it's against the run or the pass, this guy's motor never stops running. These are a few of the best shots, but I could've pulled a dozen or so examples of plays just like the ones below of Barnett running the action down and making plays outside the numbers or downfield.

It's been interesting to read and hear some analysts' feelings on Barnett against the run, citing his sack production and saying that is a one-dimensional' player. That couldn't be further from the truth. As a defensive end in an attacking front like this one under Jim Schwartz, there are multiple ways where Barnett can impact the run game. As a backside run defender, when the play is going away from him, Barnett can use the motor that you see on the plays above to chase down the ball carrier. More importantly, however, are the plays where the ball is run in his direction. Can he set the edge and force the run back inside? Absolutely. There were plenty of examples of him doing just that on tape. In this one-gap scheme, however, he'll be asked to do more than just set the edge. This scheme is about penetration and disruption.

Shot 5 - Barnett is a skilled run defender. Whether he's penetrating or making plays at the point of attack, he's a 3-down player #Eagles pic.twitter.com/xCtjdY8Xz2 — Fran Duffy (@fduffy3) May 4, 2017

Whether he's shooting a gap or being forced to take on a blocker and shed at the point of attack, Barnett can more than handle himself against the run. I expect Barnett to have an impact as a rookie and develop into a lynchpin on the Eagles' defensive line for years to come.
