I think that play fell into the "we just cannot call an Iowa foul on every play" category.The rest of the interior players for Iowa should have Tony teach them about that head butt move. Looking at it I am surprised there wasn't a foul called, but I suspect the B1G lets that go most of the time.
All ya have to do is watch film on #34 from Wisconsin to gain the ins and outs of head butting in the lane. You may even pick up the nut punch, leg sweep, and cutting underneath while a guy is elevated.The rest of the interior players for Iowa should have Tony teach them about that head butt move.
