Understood. Bill Self and Tom Izzo have had some very early bounces with some good teams as well. It can happen to the best of them. Its why they call it March madness.
That said, Fran has been coaching longer than Painter and has never made it out of the first round, despite having 12 appearances. Painter has also underachieved, but he has made an Elite 8. I think it is a false dichotomy to suggest that Fran's lack of tournament success is justified by Painter stubbing his toe here and there. Painter still has an overall winning record in the NCAA tourney and has come a game from the Final Four.
Fran's unimpressive tournament record speaks for itself. There are certainly more apt comparisons out there than Painter. In any event, I remain optimistic than Fran has built a foundation of success at Iowa, and Fran is due for a tourney run in the next few years. All slot machines pay off eventually, right?
