In the book he detailed that his wife moved to their permanent place in Nort Carolina. He was left in Pittsburgh with just his elderly parents and wasn't enjoying. Always surprised he never coached again but has worked out well. I'd love to know what he really really thinks of all of this.I think his wife didn't become ill until after he left, but the reason he left was the guy he just beat in the Super Bowl (Holmgren) got a nice new contract, and they wouldn't give Cowher that same deal.
