CBS Sports list 7 possible candidates for the position. I'm guessing the first two are not going to happen.
1. P.J. Fleck, Western Michigan: This whirling dynamo is the best thing to happen to the MAC since Terry Bowden. Sure, he's a rah-rah guy. And his motivational stuff is, well, different. Fleck is 23-10 since starting 1-11 with the Broncos in 2013. Here's my profile on him from last year.
2. Les Miles, free agent (ex-LSU coach): Crazy Les has told people privately and publicly he wants to coach. For this Ohio native with Big Ten roots, Purdue would be a comfy landing spot.
3. Troy Calhoun, Air Force: I've already been told Calhoun would be interested. The long-time NFL assistant has peaked in the Mountain West. Don't be fooled by the Falcons' option attack. Calhoun is experienced with any offense.
4. Jeff Brohm, Western Kentucky: Bobby Petrino's successor in Bowling Green, Kentucky, Brohm is 24-10 in two-plus seasons and won the Conference USA title last year.
5. Rod Carey, Northern Illinois: Coached the Huskies to the Orange Bowl a couple of years ago. Oh yeah, and he beat Purdue by 31 in 2013. Possible downside: Carey would be a second straight MAC coach.
6. Brock Spack, Illinois State: Joe Tiller's old defensive coordinator has spent eight years in FBS. Blah.
7. Mike Sanford, Notre Dame offensive coordinator: Tough sell with the Irish now 2-5, but Sanford, still in his 30s, is well respected and already has future NFL quarterback Deshone Kizer on his resume.
