deviation is there between some of the practice runs and the actual bracket. I mean it is possible a practice run may have used the same 2 teams for the #1 and #2 seeds for a region. Then it may be a plug and play situation with a few minor tweaks to account for upsets in a conference tourney or changes in which school will receive a conference's automatic bid. I am thinking about the timeline for Selection Sunday. If the final conference tournament doesn't end until sometime between 4-5pm (maybe 6pm at the latest) and the Selection Show is around 7 or 7:30pm, then that doesn't give the Committee much time especially if committee members are required to leave the room while they debate their team. Plus, I think in one of the interviews the committee chair said they started working the actual bracket earlier that day before all the tournaments were completed. Then all they needed to do is make a few minor changes once all the tournaments are complete.
