Where is he going. He just got a lifetime contract to coach KU a place that he got his coaching start at. His job just got a lit easier, why would he leave? Slim chance Manning will be head coach there.
Easier the next couple years, but not after that. Self would have been pushed to any job openings had he lost to Davidson because as great of talent as he was bringing in, a LOT of Kansas fans wanted him gone for his early tourney upsets (like Kansas wasn't known for that before he got there). Success only breeds more expectations and he just bought himself a hell of a lot more of those. His job will be easier for a couple years, but no more than a couple before the wolves start howling if he slips back to anything less than Final Four finishes.
