During the summer, 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 No. 98 Chuka Ndulue.

No. 71 Tyrus Thompson, tackle, 6-foot-5, 336 pounds, redshirt senior

Impact thus far: After a redshirt season in 2010 and limited action in 2011, Thompson has been an impact player for the past two seasons, starting 16 games in 2012 and 2013 combined. His versatility is an asset as the senior has played both tackle positions during his time in Norman, Okla.

Impact in 2014: Thompson should be a starter and key player for the Sooners offensive line, bringing experience, athleticism and production to the table during his final season in crimson and cream. It will be important for him to remain healthy throughout the year.

Long term upside: Thompson has all-conference potential if he raises his game to another level and remains healthy in 2014.

Evaluation grade for Thompson: A. When healthy, Thompson is an asset to OU’s offense. And his versatility takes his value to an even higher level. The Texas native stepped on campus as a four-star recruit and he’s met those expectations heading into his senior campaign.

Development grade for Thompson: A. A redshirt season in 2010 was the right decision for Thompson’s future. Now the Sooners get the payoff with a year of production from a savvy, veteran lineman instead of spot duty from a raw freshman in 2010.
