One of the few who could be successful coaching both in the NBA and in college. That's not always an easy transition. I feel dumb for nearly forgetting that he was the coach of that Pistons team in the mid-2000s team that won it all. They really defined the word 'team' that year. Maybe no true standout on that team (maybe Ben Wallace being Dennis Rodman-esque qualifies), but they just had a number of very good players who knew what their role was, accepted it and the team was extremely successful because of it.
If only they'd drafted better in 2003 and taken Wade, Melo or Bosh over Darko. They may have won a lot more than they did.
