2016 Oklahoma Sooners Football Countdown To Kickoff | 97 Days!

Charles Walker is a large man! Oklahoma defensive tackle, from Garland, Texas, stands at 6-foot-2 and weighs in at 299 pounds. He'll be the key for the Sooners upfront on defense this season after appearing in twelve games in 2015. Walker, a redshirt junior, has recorded 46 total tackles, with 11 for loss, as a reserve over the last two seasons but will be looked upon to lead the defensive front in the fall.

Originally a 3-star recruit by 247Sports and Scout (2-star by Rivals) Walker was the nation's 40th defensive tackle prospect, according to ESPN, coming out of high school and the 75th ranked prep recruit coming from the state of Texas. He chose the University of Oklahoma over scholarship offers from Iowa State and Colorado State.

Don't let his big frame fool you. Walker is extremely quick off the ball and has uncanny athleticism. Check out the video clip above for a great example of both.
