In my professional opinion, refereeing had a big outcome on tonight's game. The third quarter was called pretty tightly: 15 fouls combined on both teams led to 23 combined free throws in those 12 minutes. Then, the fourth quarter was called very loosely: only four fouls were called leading to three free-throws.
I don't think the game was being played any differently, it was just the standard to which Scott Foster, Scott Twardoski and Rodney Mott were applying the rules. Ideally, that would be more uniform across the entire game, but that wasn't the case tonight.
