Shoes to fill: USF

We continue our series look at some of the biggest shoes to fill across the Big East.

Up today: USF.

Who's out: Jeremiah Warren. The Bulls lose a huge contributor in Warren, who started every single game for the Bulls on the offensive line the last three seasons. That would make 38 in all for the former walk-on, who was as solid as they come on the offensive line. When last season began, there were no worries about left guard, because he was returning to that position. And his hard work was noticed by the league coaches, who picked him for the Big East second team. Consistency on the offensive line is rarely applauded. The only time anybody truly pays attention to the line is when something goes wrong. Losing a veteran sometimes shows their true value.

Who's in: Damien Edwards or Lawrence Martin. So far this spring, two players have taken reps at Warren's old left guard spot -- Edwards and Martin. Edwards is headed into his senior season after playing sparingly his first three seasons. He's only played in 12 total games, and he's played tackle. But Edwards has good size (6-foot-5, 329 pounds) and if there ever was a time for him to rise up, it is now. Martin comes from junior college, though he redshirted last season after playing tackle in 2010. Martin also has good size at 6-3, 309 pounds and is versatile. His game experience has got to help him in the competition to win the starting job.
