Blalock, Baker top preseason OL rankings

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.
