"It was one of those days where we could do that. Hats off to the seniors.They've accomplished a lot here and got a championship ring and won a lot of ballgames. So it was good to see those guys go out on a good note."McCalebb helped lead his senior class to a win with 142 all-purpose yards and his two touchdown scores."Coming into the stadium today was very emotional for me after we got off the bus for Tiger Walk and before we walked into the stadium,"McCalebb said. "I think it's good that all the seniors went out with a win."Alabama A&M quarterback Deaunte Mason went 17-of-28 passing for 186 yards and threw an interception in the losing effort.The Auburn defense held Alabama A&M (7-4) to just 22 net rushing yards on the day, with senior Kaderius Lacey leading the way with 41 yards on 12 carries.

"Our players see that in him and really respect it. Our coaches see it and respect it.He's taken a few good shots this year. He always bounces back, and he does not want to come out of the game. He's done that several times, but I think that's just kind of the case and point for him with how much football means to him, and how much it means for him to be out on the field."Alabama A&M got on the board with a score on the opening drive of the second half, when Deaunte Mason punched in a 1-yard touchdown.After another McCalebb score, the Aggies gave up a team safety when an errant snap went over punter Chance Wilson's head, and was batted through the end zone.Auburn sophomore Trent Fisher returned an Alabama A&M interception 60 yards for a touchdown with just under three minutes to play to give the game its 51-7 final score.The Tigers' 512 total yards were the most by an Auburn team since the Tigers' national championship team totaled 519 yards against Oregon in 2010.
