You can also blame Self. Not only did he leave Udoka in, but he kept him on the post because he wanted him to post up Freeman, even though he knew Freeman would foul. Freeman did 3 times before Self took Udoka out of the play in the corner, and when they did that, KU missed a layup but got the putback. Next possession for KU, they sent Udoka back down to post up, and threw the ball to him, and Freeman fouled picking up his 5th.
So like I said, not only did Self leave Udoka in, but he had the offense try and use the "mismatch" against Freeman to their advantage, only to be fouled because that's why Freeman was in the game for. When KU took Udoka out of the play, KU scored.
They tried to take Udoka out of the play against Lattin, but then called timeout. During the timeout, Lattin talked with Kruger about should he guard Udoka out there, knowing Udoka can't shoot a 3, and wouldn't screen in a corner, and Kruger told him no, stay home and help, and sure enough, KU tried some dribble crap and chucked up a 3 with a hand in their face and missed.
