If the kid's gonna leave his hands down and pretend he can attribute box, he should at least know to to move his legs instead of leaning back really far to avoid a combination. That's a beatdown, not a fight. He should've at least gone for something before the inevitable KO.
Aggressive thug is just sealing the deal with the punches on the ground. Whatever caused defensive thug to step up, he probably won't do so again, but people can have delusions of adequacy if they take one off-balance shot and can get up shortly after.
:lawl, street brawl commentary from yours truly.
