throwdown or two back in the day. Boys workin' off a little steam. Happens all the time. If you got a buddy gettin' jumped you have his back. It's different when a guy has a persistent problem with anger issues and such and never grows up, but these incidents in a super-competitive environment are to be expected from time to time and just need to be managed appropriately.
You break it up, and then get on with it.
I honestly don't see why people make such a big deal out of it unless someone crosses the line in some way, and a cheap shot punch isn't over the line. Punk move, but not over the line, and we don't even know if Nacua got cheap-shotted himself. Back in the day if you cheap-shot me, all unspoken rules in fighting are out... I'm going after you and your boys whether you think it's a cheapshot or not.
Lots of drama over nothing imo.
