I thought it was pretty obvious even in real time. He clearly made contact with Buddy which makes it all the more obvious (the violation is actually for breaking the plane of the baseline). I get that they might not want to call a t in that situation, but at least blow the whistle, warn the guy and back him off. I've definitely seen refs do that.
Oh well. Still a great game. OU wins that game with sharper free throw shooting and/or better ball security late in the game. We'll definitely get them in Norman.
