Riley has done well in his 12 years coaching Oregon State, all things considered, but this still seems like a kind of strange fit to me. He'll be 60 years old when the season starts and never has coached (or, as far as I can tell, lived) in the Midwest. In fact, the only player on the Oregon State roster from a Midwest-ish state is a sophomore RB from Missouri.
It seems like it could take him some time to get up and running there, which might not be what you want from a 60-year-old coach.
