Crimson Countdown: S Quentin Hayes

During the summer months, ESPN.com is taking a closer look at each scholarship player on Oklahoma’s roster in our Crimson Countdown series. Each day, we analyze each player’s impact on the program since arriving on campus, his potential impact this fall, and his long-term projection. Starting with No. 1 Dominique Alexander, the series follows the roster numerically through our final analysis of No. 98 Chuka Ndulue.

No. 10 Quentin Hayes, safety, 6-foot, 189 pounds, senior

Impact thus far: Hayes' impact was minimal until last season. He redshirted in 2010, saw limited duty in 2011 and missed the entire 2012 season. His junior season was a breakout campaign with 75 tackles including 40 tackles for loss, two interceptions, two forced fumbles and one sack.

Impact in 2014: Hayes should start and bring a veteran presence to the Sooners’ secondary. He’s a proven playmaker who will provide peace of mind for the defensive coaches with his consistent play.

Long-term upside: Hayes has the ability to earn all-conference honors as a senior because of his versatility. He has the ability to make plays in the running game and hold his own in coverage, making him a valuable asset.

Evaluation grade for Hayes: C. This grade could jump to a B with a solid senior season, but the Sooners have only one good year of production out of the four years he has been on campus. That's the only reason this grade is a C. When he's healthy and available, he's an impact player.

Development grade for Hayes: B. The Sooners have done a pretty good job with Hayes' development. The senior safety is the one who took himself out of the equation after his redshirt freshman season with his 2012 suspension. When he has been healthy and available, the Sooners have found ways to use his skills.
