You're fighting a losing battle. Those who believe you have to have experience to win a title will never budge. If we were to win this year, they would say it was because WG, SKJ, Wynyard and Brad returned, even if none of them see a minute in the title game. It started with you can't win with any freshmen, then it moved to you can't win with a freshmen PG, and now it is, well you can't win starting 5 freshmen. But once someone does that, and someone will, it will be you can't win with all freshmen.
People just aren't willing to admit that there is no grounds by which to tie tournament failures to experience. Are there freshmen laden teams that lose in the tournament? Yes, but there are also senior laden teams losing as well. How about this one, Cal's most experienced starting five, lost in the second round. Cal's most freshmen laden starting five, lost in the championship game.
