Aside from the apparent fact that one of these individuals was in the "mounted" position, I don't understand the repeated references to MMA. This wasn't a physical altercation involving skilled combatants with hour upon hour of practice in striking, grappling, and counter techniques. And to the best of my knowledge, neither one of these "unwilling" participants was trained in street defense.
Essentially, GZ and TM were untrained
strangers engaged in a street fight. In terms of style and technique, you might find a better representation of their struggle at the local schoolyard.
MMA has been referred to as controlled
chaos; implying weight classes, gear, rules, referees, discipline, strategy, rigorous training and practiced technique. Conversely, whatever happened that night on the greenbelt between TTL & RVC was utter
chaos - involving a firearm. Bad analogy folks; we aren't talking Silva v Sonnen here. Enough with the "from the top position, he coulda dropped elbows" hyperbole.
The fight had moved back on to the grass.
The police had been notified and were moments away.
*Don't bring a knife to a gun fight, and don't bring a gun to a fist fight.
And if you want to go home, don't provoke a situation you might not be able to control simply because you're "packing." Oh, I forgot...he forgot. Never mind!
