None of these three knows how to fight... So the winner ultimately would be the one most likely to spazz out, press the attack and get the other guys in a quick pindown on the ground.
So Balmer would probably win, because he's most likey to go nuts and if he gets one of the other two in a pin they aren't getting him off.
He might not have any endurance sure... but have any of you guys actually seen a real fight? It's not like an anime or boxing match. At most a real no holds bard fight among amateurs is lasting 3 minutes.
Only thing stopping Balmer is if one of the other two has some kind of fighting training their profiles don't suggest or if they team up.
Dude is just way too intense compaired to the other too..
Iwata likely is in last place. Seems waaaay to laid back.
