Getting a "name coach" from a powerhouse school doesn't work well for Purdue. Akers was used to getting the top talent in the state, and his game planning/recruiting did not work well at Purdue. He didn't get the kids who were good enough to hide his weaknesses. Someone like Fleck might be a better choice because he is very used to working with less developed kids. He develops them, and puts them in winnable situations, which is an important skill. That is the type of coach Purdue needs. Not Les Miles.
I've said it a bunch already, but this board seems laser focused on hiring a current head coach. Maryland made a pretty good hire, at least imo so far, and he was a defensive coordinator.
I think a school like Purdue is in a similar boat to Maryland. Maryland also fired Edsall mid-season and spent some time chasing some bigger names, realizing it wasn't going to happen and then plucked a pretty solid coordinator who has already made some big improvements at Maryland that fans are excited about.
