Lighty looked like he slipped to me and contact was incidental (let me clarify that: he appeared to be falling to the floor before Doellman touched him...it could well have been called). Oden's foul probably looked worse than it actually was, but I certainly have seen intentional fouls given in that situation before.
Regardless, I think the talking point has to be XU's loss of composure down the stretch. Doellman's lazy inbounds pass to Lavender was an absolute killer.
In any event, anyone blasting Justin Cage needs to look at the box score. He played one of the finest college basketball games I've seen in a long time, and if OSU doesn't hit a really low-percentage shot, his final miss would have been academic.
