Duke player turned around and hip checked Monsanto in transition. Not exaggerating
I'll be the first one to complain about dook, but I did go back (as ESPN with all their technology never showed it again) and look at it. The dook player looked more like he was trying to take a charge then Monsanto tried to avoid him but ran into his knee. The base line ref was in a perfect position to see that action since it was right in front of him.
If was a foul, but I can't say it was a body check like we've seen in the past.
