I'm not the best lip reader, but when they showed the replay on TV, it looked like Les screamed across the court at the ref that the call was bull****.
That's what it looked like to me as well.
Didn't cost us the game, though. I saw the second half, and this was the first I had watched of BU since the ISU game. They definitely looked improved, but I agree that they panicked for a stretch late after UNI went ahead.
