There are a couple reasons I still think Madsen is a possibility...
that I haven't seen yet on this board. First, I'm pretty sure his wife is from Utah county and is a BYU alum (correct me if I'm wrong about that) and maybe she would want to come home? Second, I was watching an interview where he seemed quite disappointed by the demise of the Pac-12. Plus, flying from CA to the East Coast every week for conference road games sounds pretty miserable.
Also, like some others have mentioned on here, his statement earlier didn't seem all that concrete to me. I've heard other coaches say similar things and then leave. So who knows? He surely wouldn't be cheap though.
