2 of the most egregious, in my likely-to-be-biased opinion, was the charge called on Tillman when he passed to Bingham for an oop (was 18-18 at that point with MSU surging), and then a couple of plays later when they called Marble for a foul where Maxey jumped behind the hoop and had nowhere to go and bounced it off the backboard. And if I'm being picky, they missed a travel on Hagan's breakaway and Gabe Brown got absolutely hammered on a breakaway dunk with no call at all - but I think both of those were in the 2nd half when the calls seemed pretty even.
After I rewatched on YouTube, not a ton of other calls stood out. But the first half was definitely hard to watch, just from all the stoppages. No flow, most points from FTs etc.
The part in bold: Hagan walked a mile. He took three steps. No doubt about that. However, Winston's being fouled (Richard's fifth foul) on a short shot and a free throw was more of him running into Richard than anything else.
Top to bottom I though it was close to evenly called; however, the game would have been better for both teams if the refs had loosened up on their calls.
