Over the summer months, SoonerNation will take a closer look at each scholarship player on Oklahoma’s roster in our Crimson Countdown series. We'll analyze each player’s impact on the program since they arrived on campus, their potential impact this fall and their long-term impact in the daily series. Starting with No. 1 Tony Jefferson, the series will go in numerical order until our final analysis of No. 98 Chuka Ndulue.
No. 14 Aaron Colvin
Defensive back, 6-foot, 176 pounds
Impact so far: Colvin played his way out of a redshirt season in 2011, even earning his first start against Texas in the Red River Rivalry. He played cornerback as a freshman and finished with 34 tackles in 14 games. As a sophomore, Colvin moved to safety in order to get him on the field with Jamell Fleming and Demontre Hurst manning the cornerback positions. He started 12 games to finish tied for the team lead with 84 tackles. At strong safety, Colvin provided the ability to cover tight ends and slot receivers while also proving solid in back end coverage.
During his first two seasons, Colvin has been maximizing his potential and is arguably the most underrated Sooner on the roster. He’s a playmaker who led the team in tackles yet didn’t make honorable mention All-Big 12. He's a terrific example of quality evaluation by the Sooners coaching staff.
Impact in 2012: Colvin could end up starting at cornerback or safety this fall. The junior’s shoulder injury prevented him from participating in spring football so new defensive coordinator Mike Stoops hasn’t slotted Colvin into a permanent role in his defense. But he’s one of the Sooners top 11 defenders so he’ll be on the field and making a significant impact.
Impact in 2013 and beyond: Unless he has a stellar season and elects to leave early for the NFL, Colvin should be one of the top playmakers on the squad and serve as a cornerstone piece of the Sooners defense in 2013.
