Crimson Countdown: C Ty Darlington

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 56 Ty Darlington, center, 6-foot-2, 286 pounds, junior

Impact thus far: He's provided backup depth behind All-Big 12 center Gabe Ikard during his first two seasons in Norman, Oklahoma. Darlington played in nine games (one start) as a true freshman in 2012 then played in three games in 2013.

Impact in 2014: Darlington will battle to replace Ikard at the center spot and has plenty of experience at the position meaning he should, at the very least, provide a quality option. The Sooners will strive to put their best five offensive linemen on the field so Nila Kasitati could also be a option at the center spot in 2014.

Long term upside: Darlington should be a valuable contributor as a starter or quality backup for the next two seasons.

Evaluation grade for Darlington: B. Heading into his third year on campus, Darlington has already made an impact and started a game despite playing behind an all-conference center during both seasons. He hasn't been a major contributor but he provided depth and peace of mind as a underclassman and could rise to starter status this fall.

Development grade for Darlington: B. The only thing the Sooners could have done is play Darlington more during blowout games just to get him added game time and seasoning as he prepared to battle to replace Ikard during preseason camp in August. Outside of those moments, Darlington's development has been solid.
