I don't know I've seen a lot of fights throughout the years this one was pretty weak in my opinion. Not saying I condone it but it was a glorified wrestling match.
Terrible behavior but I would be surprised if anything comes of it.
I guess I was more speaking to the last 10-15 seconds. That second set of guys fighting it looks like his head is slammed into the concrete wall pretty damn hard and then I don't see him moving and the dude is unloading on the motionless guy.
