Bielema remains tight-lipped on new Illini defensive play-caller

Illinois football coach Bret Bielema did not disclose the identity of the team's incoming defensive play-caller on October 2. Following a disappointing 42-19 loss to Ohio State, he acknowledged that changes were needed to improve a defense that ranks poorly nationally. Reports suggest the new coordinator will likely come from the current staff. Inside linebackers coach Roger Cooper is considered a potential candidate. Bielema also emphasized players' commitment during the transition. The Illini's shaky defense will face a daunting test against Purdue, a team that has excelled offensively.
