Walker didn't gain a lot of fans in Norman with his exit from the Sooners midway through the 2016 season. He played well in the team's first four games (seven tackles, 2.5 tackles for loss), but suffered his third concussion against TCU. After one month trying to recover (and denying he was going to leave), he decided to quit the team to focus on preparing for his professional career for the sake of his daughter. In 2015, Walker didn't start a game but still managed to earn second-team All-Big 12 recognition with 10 tackles for loss and six sacks. That followed a redshirt freshman season where he showed flashes (five tackles, 0.5 sacks against Clemson in the Russell Athletic Bowl) but missed five contests with a knee injury.



Disruptive and productive as a sophomore in 2015. Can be tough to handle when motor is cranked and he's working the gaps. Comes off the snap with good get-off. Able to rip through a blocker's edge with good violence once the door opens up just a little bit. Has upper body power to set a strong edge. Plays with unusual agility and athleticism once he's into the backfield. Able to redirect his weight for sudden change of direction. Plays on his feet. Shows ability and play speed to chase down running backs and quarterbacks headed for the perimeter. Operates with a big closing burst and an extended playmaking radius. Hands show power and potential in both run and pass. Works his hands and feet in unison as interior rusher.


Has had concussions in each of last two seasons. His football character called into question by coaching staff after he failed to come back from October 1 concussion and left team with two regular season games remaining to prepare for NFL draft. Effort level and motor fluctuates. Was a relative non-factor in all four of the games he played. High cut and struggles to maintain his ground against double teams. Lacked urgency as a pass rusher that he showed in 2015. Needs to add a rush counter when initial charge is foiled. Will lay on blocks at times. Needs quicker shed with tackle-ready posture.

"I'm not really a fan but I'm sure our coaches will be. He has talent but he's just so inconsistent. He has quickness and strength but then will just disappear during the game. He has enough flashes on tape that I'm sure our coach will want to work with that." - NFC regional scout

Bottom Line

Disruptive defensive tackle with the initial quickness and power to become a factor for a one-gapping, upfield front if he can ever put it all together. Despite his flashes, Walker's career starts can be counted on one hand and 2016 was a complete loss of a season. NFL personnel men are likely to get harsh reviews from the Sooners coaching staff and teams will need to do their work on Walker's concussion situation, but his athleticism and potential give him a chance to become an NFL starter.
