Player: Travis Lewis
Position: Starting weak side linebacker
The rundown: A year after breaking Brian Bosworth's freshman record for tackles in a season, Lewis led the Sooners in that category again last year with 109, 56 of which were unassisted. He also had 9.5 tackles for a loss of 23 yards to go along with an interception, forced fumble and a pair of passes broken up. All of that helped him earn All-Big 12 first team honors.
Expectations for 2010: Lewis is the personality and catalyst of this defense, and simply put it will go as far as he takes it. The Sooners need some of the youngsters on the defense to step up, and Lewis is the right person to get those guys in line to do so. He will lead the Sooners in a number of categories and probably rack up some individual awards at the end of the season, but don't expect him to be satisfied with any of that unless OU wins a Big 12 Championship and possibly a National Championship.
