I think that's a pretty big assumption. I'm not saying Rudolph should be suspended because of Garrett's suspension. I've seen plenty of posts on here say the same thing, that Garrett's punishment is completely justified.
What Ogunjobi did was a shove from behind. If he wanted it to be more, it would have been. Using phrases like "went after" and "blindsided" is making much more of it than what it was, IMO. But, again, if you wanna give him a game, I can see it. The altercation appeared to be over and he shoved the guy anyway.
Rudolph tried to rip a guy's helmet off, repeatedly struck him in the groin, and then charged him after the two had been separated.
Greg Robinson was ejected from a game earlier this season for kicking another player. Why shouldn't Rudolph also miss time?
