There's a distinct bad guy though.Garrett made an unnecessary and hard take-down of Rudolph. That should have been a penalty/fine/whatever - and also should have been the end of it.
Rudolph took umbrage and began trying to yank off Garrett's helmet (for reasons known only to him), and then planted his cleats in Garrett's groin. At that point they were separated and it looked like things were over. Then Rudolph came after Garrett again and got a helmet to the head for his trouble. Then several Steelers took Garrett to the ground and began beating and kicking him.
I'm having a hard time finding the good guy in this story.
