Playing behind Josh Thompson at noseguard and Sen'Derrick Marks at tackle, Sims' versatility to play both spots up front has earned him just as many snaps thus far as the starters.
"If you know one position you should know the other position," Sims says. "There are certain things at the three-technique and there are certain things that the noseguard does. In some situations the nose does different things than the tackle, but it's almost the same."
Sims has helped an Auburn defense that has not allowed a touchdown for the last nine quarters.
Sims, who played in just one game in 2004 while redshirting, wasn't part of the lineup in 2005 and quit the football team. However, he came back during the off season, worked hard and earned his stripes.
"It's a lot of fun," Sims says of being in the rotation. "It's way different than playing in just one game. You go out there, have fun with your teammates, everybody rallies around you and cheers you up."
Playing three-technique in run situations and nose in pass situations, Sims hurt his knee against LSU. But with his changed attitude he fought through the pain and made contributions even after the injury.
"I came back and participated in the (last) drive," he notes. "I didn't want to quit. I just wanted to show my teammates that I was there for them and push through it."
Sims is practicing this week and spending time in the training room this week trying to get healthy for the Buffalo Bulls this Saturday at 1:30 p.m. Through three games he has seven tackles, three for a loss, two sacks and a forced fumble.
