There have been a lot of long-tenured coaches in college basketball, maybe not 47 years, but once you're a basketball coach, you're basically a lifer.

I wouldn't say it's "baffling" that he only won 1 championship, the NCAA tournament has a big randomness factor to it. You have to beat 6 teams in a row, most of which are really good teams and are playing to keep their season alive. If your team has one poor shooting night or the other team shoots 70% from 3 or something flukey, your season is over. It's very difficult just to make it to The Final Four. No doubt he would have liked to win one or two more, but it's much better to have one than none!
