One of my best friends is 6'4, 250lb - not a trained combat fights But He can fight.
In the real world dudes like that are winning 95% of one v ones.
Most dudes is getting laid out on th approach. He's too good at fighting to let a small nikka get close enough to land a punch.
Seen this breh and been in brawls with dudes. Only 1 v 1 that troubled him was with a semi trained dude.
Also most fights as adults are under the influence. You not ducking and diving a much bigger and taller dude when ur tipsy. Big fella has hit you with the hand of Zeus before you can fire off.
