One of the heroes of Auburn's unexpected run to Pasadena won't be back next season. The school announced on Thursday that running back Tre Mason will forego his senior season to enter the NFL Draft. Mason had a spectacular season for the Tigers, rushing for 1,816 yards and 23 touchdowns. While he was solid all year long, Mason didn't really explode onto the national scene until the end of the year when he rushed for 164 yards against Alabama in the Iron Bowl and followed that up with a 304-yard and four touchdown performance against Missouri in the SEC Championship. Those performances helped earn Mason a trip to New York as a Heisman finalist, an honor he proved worthy of after rushing for 195 yards and a touchdown as well as catching a 42-yard score against Florida State in the title game. Fittingly, on Mason's final run in an Auburn uniform -- the 37-yard touchdown that gave Auburn a 31-27 lead with 1:19 to play -- he broke Bo Jackson's single-season rushing record of 1,786 yards at Auburn.
