Utah State quarterback Chuckie Keeton says he won't be too overwhelmed on Sunday when the Aggies visit Tennessee at Neyland Stadium. The dual-threat senior quarterback for the Aggies is anxious to make his return from injury before a big crowd and on a national stage. Keeton hasn't played since last October against BYU, when he injured the ACL and MCL in his left knee and had to sit out the rest of the season. The Aggies wound up 9-5 last season, falling to Fresno State in the Mountain West championship game, but defeating Northern Illinois 21-14 in the Poinsettia Bowl. Keeton's return is already generating a lot of attention, and Utah State already has a website touting its quarterback for Heisman Trophy consideration. Tennessee defensive tackle Jordan Williams even said Keeton reminds him a bit of Mariota. In his five-plus games last season, Keeton still passed for 1,388 yards with 18 touchdowns and just two interceptions.
