Texas' Justin Blalock has an impressive résumé. USC's Sam Baker has stepped out of the shadows. Oregon State's Jeremy Perry is ready to make his mark. Take a look at the preseason rankings for the nation's top returning offensive linemen.
1. Justin Blalock (Tackle), Texas, SR, 6-foot-4, 328 pounds
Blalock lacks ideal athleticism and also has room to improve from a footwork standpoint, which could keep him out of the first round of next year's NFL draft. Purely from a college football perspective, though, Blalock boasts an incomparable résumé. Entering his senior season, the Longhorns' mammoth right tackle already has 30 consecutive starts, two first-team All-Big 12 awards and one national championship under his belt.
