You don't notice, but most of the "crap" officiating this year has directly affected the "little guy" teams that aren't supposed to win (except UK - we are the lone big-named target for "crap" officiating).
It's crap officiating, but oddly the crap this year has oddly stayed on one side of the court at the most crucial times. These refs know what they're doing, and they know how to make or not make calls on what players and at what time, to give their favorites the edge.
Two straight games for UNC, both with nearly identical first halves - three and four key starters on the bench with 2 fouls, yet UNC had only had a few bench players with a couple each.
You listed only a few earlier that were bad calls that could have hurt UNC, but 4 of 5 fouls alone on Collins (all wildly-phantom) were enough to trump those you listed that seemed to go against UNC. That's just one Zags player! Then note that they had three of their most important big men fouled out or nearly fouled out with 5 minutes to go in the 2nd half, while Meeks manhandled everyone without nary a whistle tweet.
