No. 4 LSU's depth faces big test at No. 10 Florida

Without Blue, some of LSU's other talented running backs will get an opportunity. Kenny Hilliard, Spencer Ware and Michael Ford have all had spectacular moments during their careers and freshman Jeremy Hill is showing promise. Hilliard and Ware are also big and tough enough to fill in at fullback.

Dworazcyk is a sixth-year senior and a former starter at guard. He said he feels comfortable moving to either tackle spot, and added that many LSU players are adept at multiple positions, giving the coaching staff a lot of flexibility.

Mathieu's departure un August forced LSU to start freshman Jalen Mills at cornerback, with Mills moving to nickel back and redshirt freshman Jalen Collins coming in at cornerback in passing situations. Mills has a pair of interceptions and Collins has broken up a pair of passes that wound up being intercepted by a teammate on the deflection.

"We don't recruit these guys for no reason. They're great football players," said receiver Russell Shepard, who works against Mills and Collins in practice. "Those guys are ready because the coaches do a great job preparing them and our leaders on the team do a great job of showing them how we play our style of football."
