Kat Kid here with just a few observations.
1. Yes the refereeing was bad, particularly bad throughout the game. Inconsistent and indecisive. Way too many offensive fouls, way too many flops rewarded, some bad calls where the defender was vertical, just bad all around.
2. The absolute dumbest thing I see is people looking at FT numbers and then using them as absolute proof the officiating was biased. KU fans were hilariously trotting out the fact that K-State shot more free throws in Allen as proof that they had been cheated that game prior to the no call on the travel. It is one of the worst types of talking points.
3. I don't think the Brown call or the out of bounds calls were bad calls. If you look at the replay, you can see Brown slap him on the arm and that is what causes the ball to go in the back court.
4. The problem with the Brown call and lots of others was the indecisive nature of the refs. Several times you could see them waiting to weigh what outcome would be most just and then retroactively inserting themselves to assure that happens. It is why there were so many inconsistent calls, because they were trying to do make ups and respond to the flops etc. It was a bad officiating environment and so it created bad calls. Really good refs like Jerry Pollard or Higgins will talk to the players even in the middle of a play to warn them if they are fighting for position on the blocks or pull them aside and talk to them during FT or before a time out. Bad refs are not confident enough to do this and so are indecisive when they have to blow the whistle and then don't want to talk about it afterward.
5. oscar's T is not being criticized enough. It absolutely killed any chance of winning that game with the game still very much in doubt. It is inexcusable. The time to criticize the refs was a long time ago, as dax rightly pointed out. And oscar just stands there with his jaw open and doesn't say anything. Working the refs isn't something that is necessarily going to pay dividends if you aren't an elite team/coach anyway, but at least know the time and situation. Is it at all surprising that our players choke and find excuses for not finishing when our own coach makes such an enormous error with the game in the balance?
