Damn I have to side with Terry on this. There was no shove and Bert (as he's called in Wisconsin) probably out weighs Robinson by 50 lb at least. He does fit the team's mascot image a pig and a hog.
I don't think it is a play on the name as much as it is because he looks like a fat version of Bert from Sesame Street.
Fault is on the ref. Simple example: That would be like a baseball umpire awarding first base simply due to the fact that a batter drops the bat and acts like ball grazed him. If the ump didn't see it...
