Oklahoma position grades: Defensive back

Before the Sooners' 31-14 win over Iowa in the Insight Bowl, Jake Trotter and Brandon Chatmon analyzed each Oklahoma position group. Now, the SoonerNation staff is giving each position a grade for its performance in 2011.

Grade: C+

Ninety-five percent of the time, the “Sharks” played an “A” game. But the five percent they didn’t proved to be calamitous. Replacing cornerback Jamell Fleming will be a challenge. He was OU’s best defensive back all season, despite missing two games due to minor knee surgery.

Grade: B-

The Sharks had their good days and their bad days... and their really, really bad days. Cornerbacks Fleming and Demontre Hurst along with safety Aaron Colvin had very good seasons but to say OU struggled against passing teams is putting it mildly. Safety Javon Harris made several great plays to open the season but began to give up more plays than he made as the season progressed. Sophomore Gabe Lynn struggled at times and the overall depth in the secondary was nonexistent. Fleming, Colvin and Hurst get all A’s everyone else gets a C. Or worse.

Grade: C-

Labeled the "Sharks" before the season started, no group had more ups and downs than the secondary. It wasn’t all bad, though, as players like Colvin and Tony Jefferson are showing the future will be bright. Fleming had a great senior season, but the losses to Texas Tech and Baylor are a huge black eye on the group. Harris and Lynn struggled at times and will need to bounce back in 2012.

Grade: C

When they were good, they were good, but when they were bad, they were incredibly bad. In losses to Texas Tech and Baylor, the Sooners' secondary was the worst position group on the field. Without the veteran presence of Fleming next season, it will be interesting to see how the defensive backs adjust to new coach Mike Stoops. The talent is there, but the consistency must improve in 2012.
