Looking back at OU's 2012 class

NORMAN, Okla. -- The Oklahoma coaching staff is working toward finishing off the Class of 2013. As signing day approaches, SoonerNation analyzes the players that inked last year and their prospects going into next season after one year in the program:

QB Trevor Knight: Even though he never saw the field, Knight was as impressive as anyone from this class, running the scout-team offense with plenty of precision and playmaking. The starting QB job is Blake Bell's to lose, but Knight's trajectory suggests he could be a factor in the derby.

RB Damien Williams: With Dominique Whaley ailing from an ankle injury, Williams took over the starting job in October, and ran with it. Literally. Williams had four touchdown runs of 50 yards or more, supplying the Sooners with the home-run threat on the ground they had lacked since DeMarco Murray's freshman season. If he can stay healthy for an entire season, Williams could be OU's first 1,000-yard rusher next year since Murray.
