He is a punk, a completely untrained strong breh nearly got out of all of that...
Green Shirt:
Do a sloppy lateral throw?
Take someone's back and lose the position?
Try again for an triangle and nearly get body slammed?
Hit a sloppy x guard?
Threaten heal hook?
A legit player would have:
Not even let it get to that level and showed restraint...looks like he wanted to just try his techniques on the first guy that got in face outside of school...
Basically...this video is old af too.
But

all around
-White dude wasnt prepared for the punch and pulls half guard
-White dude eggs on the situation in an attempt to be able to use Jiu jitsu in the breh
-Everyone can see the breh was tryna sneak him...dude was winding up and telegraphing that punch for awhile
In a situation like that I wouldn't have egged on the situation with "I'd beat your ass"
If dude swinga on me I plan to trying to sweep,slam dude to the ground standup and just avoid further punches...no way I'm gonna pull fukking guard or even mount and pound on someone when his boys are around.
