This one was really obvious. The crowd went nuts, then they called a facemask on CU about 3 plays later that was not a facemask from what i could tell as a make up call. Then the flag on Dennard for PI the possession after that was garbage. I think after the crowd went nuts on those two calls you saw them get alot more careful about what they were doing, hence the flag pickups. I honestly think they had it in their mind to pull a screw job, but thought twice after realizing what kind of position they were in.
