Iowa's Coach Tom Brands and Sanderson get into it after some confusion (or is it "confusion"?) over a whistle. Action is around 7:40.
HVHN has your story:
Wade clearly was wrong in the takedown attempt but, in his defense, there didn’t seem to be any reason for the ref to blow his whistle. Erekson could see the ref wave his hands and relaxed but Wade had his back to him and couldn’t see it. Given all the whistles blowing on all the mats it’s hard to blame Wade. The ref’s responsible for making sure that both wrestlers know what’s going on.
