AUBURN, Ala. u2015 Auburn didn't know what it had in running back Tre Mason heading into the 2012 A-Day Game.
A thousand yards rushing that season, and 1,816 yards the next season, the Tigers knew they had a winner.
The search to produce Auburn's ninth 1000-yard rushing season in seven straight years will continue in Saturday's A-Day Game at 3 p.m. in Jordan-Hare Stadium on the SEC Network.
The list of spring contenders are familiar, with a few twists. Jovon Robinson and Roc Thomas are the returning tailbacks.
