Inexperience at Defensive End
The biggest question mark for the 2015 defense is how to replace both starters at defensive end in Deion Barnes and C.J. Olaniyan as well as key reserve Brad Bars. Barnes and Olaniyan may be equally difficult to replace- while Barnes excelled at creating havoc in the backfield, Olaniyan was a steady presence who was tremendous against the run and had a knack for showing up in big games.
Garrett Sickels and Carl Nassib seem to be set as the new starters, with Evan Schwan, Curtis Cothran and possibly true freshman Torrence Brown waiting in the wings.
