My only theory is that the Big East didn't challenge itself in the regular season in out of conference match ups. In conference games do not prepare a team for tournament play. A coach is given multiple seasons of tape to prepare for a conference opponent. Good tournament play is a function of a coach's ability to prep for a good OOC team in a moment's notice (ala pre-conference play, midseason tournaments, or NCAAT). And in the Big East's case, they didn't play a lot of good OOC teams.
