WEST LAFAYETTE, Ind. -- I'm covering Purdue's media day festivities throughout the morning. Check back later for plenty of Boiler updates (I always wanted to write that).
For now, here are three questions facing Purdue this fall:
How will the team navigate its challenging schedule?
The Boilermakers didn't make it easy on Tiller in his final season. A normally manageable nonconference schedule turns treacherous this fall, as Purdue plays Oregon, Central Michigan and annual rival Notre Dame. Purdue also has road games against Ohio State and Michigan State. The good news is both the Oregon and Central Michigan games are at home, where Purdue went 5-2 last season. Having a senior quarterback like Curtis Painter usually helps, but the schedule provides both Painter and Tiller several chances for validation. Big games have recently been the knock on Purdue, and the slate is filled with them.
Greg Orton was often overshadowed by Bryant, but the senior has been consistent and should fit in nicely as a featured receiver. Purdue will ask for more from Desmond Tardy and continued contributions from running back Kory Sheets, who caught 30 passes last season. The spotlight also will be on junior-college transfers Aaron Valentin and Arsenio Curry, who weren't brought in to watch. Valentin joined the team this spring and got adjusted to the system, while Curry must play catchup in camp. Keller was a unique talent and can't be duplicated, but junior Kyle Adams brings some experience to the tight end spot.
Who will fill the playmaking gaps on defense?
The Boilermakers lost their best pass rusher in end Cliff Avril and their best overall defender in cornerback Terrell Vinson. Of the two units, the line looks to be in better shape to fill the void, especially with Alex Magee and Ryan Baker occupying the interior. The secondary is a different story, but Brandon King's move from safety to corner could be a good solution, especially if safety Torri Williams can finally stay healthy. Junior-college transfer Dwight Mclean should provide depth at safety, but Purdue will look for more from cornerbacks David Pender and Royce Adams.
