The NCAA tournament does not care how a team wins its game, only that they win. If they play one of the worst halves of basketball possible or an opposing player temporarily forgets that basketball exists in a limited amount of time and does not extend infinitely past the temporal limits of human experience or if the broadcast is temporarily halted to show us a message from Buckingham Palace but they still win in overtime then they still get to live another day.
Northwestern and FAU played the first half they had been placed in some sort of TruTV prank show where they replaced the baskets with narrower novelty rims from carnival games that made it all but impossible for a ball to successfully pass through the hoop.
