Hate to do this because it sounds like whining, but you asked so here goes.
Last year against Villanova. I wouldn't say it caused KU to lose but it definitely helped Villanova. KU was down by 2 with the ball with less than a minute on the clock. Graham splits a double team at half court, gets tripped, falls and in the process of trying to recollect the ball gets called for a foul. So instead of KU shooting FT's with the opportunity to tie, Villanova has the ball. Plus it was Graham's 5th foul.
Yeah that's not really how it went down at all, he lost the ball and took a guy out at the knees. Nice try though Champ
