I thought the referee did a good job on the play. He signaled the foul, and then made the motion to count the basket. The signal was made in the direction of KU's bench, which could've looked like he was pointing that way. He never went to his head for the PC call. Perhaps he shouldn't have turned while making the signal, but that's pretty small beans.

That really was a TOUGH game to call. A lot of contact, a lot of physical play, and a lot of fouls. It may have seen a little over-the-top if the refs "sold" every block/charge. I thought the refs AND the players did a good job of keeping the game from getting out of hand. There had been a good amount of flagrant conduct in last year's game, and lots of talk about "no love lost" between the team in the media... but players on both sides conducted themselves with great sportsmanship.
On a related note, I found something pretty interesting - every time #0 on KSU was whistled for a foul, he went over to the ref, put his arm around him and gave him a pat on the rump. There are a lot of players that try to endear themselves to the officials, and this is certainly better than the other end of the spectrum of yelling and screaming; but at what point does this get to be too much and you tell a player to knock it off?
