The vid that explains it all

It's funny, this video shows some 50 + "pushes" by Khan, but I really didn't even notice it or give it a second thought until the ref started deducting points. I'd really thought the point deductions were going to be for pushing Peterson's head down and not for pushing him off. I can't recall seeing another major championship fight where 2 points were deducted for "pushing", that was just totally uncalled for.

PS. I'm surprised this dumbass ref didn't DQ Khan after the 2nd point deduction, then there would have really been an uproar.
