Whoever knocked the other guy out. Street fights don't care about statistics or probability too much. Normally the victor is decided by who lands the first sucker punch and stomps the other guys head. If you want to talk advantage, Orton would have the advantage of height and weight (mass = power in most cases), but striking and moving advantage would go to the boxer. You also didn't mention the quality boxer the 15-year old is. Just because he's been practicing boxing for a few years doesn't mean he's any good at it. If he's good, he has an advantage, if not, he loses because he's fighting a taller, heavier guy who is older (so he may have had more street fighting experience). I don't know Orton's experience though because I don't follow wrestling. For all I know he has some actual fighting background, otherwise I assume he's a body-builder/entertainer which grants him no points in a fight.
This is always like asking who will win, a badminton player or a tennis player?
Boxers have an advantage in a street brawl in that there is no ring. They can move. And boxers are intimidating because they can hit really hard and have tremendous hand speed.
Wrestlers have the advantage that once they get hold of you, you are in their web.
Whoever applies their technique first usually wins. If the boxer smashes your orbital, crushes your nose, or knock you cold, he wins. If the wrestler gets a good grip.....he wins.
MMA and ultimate fighting is not a good measure, as the rules and cage favour grappling.
There is one last measure....how good is each at what they do, how committed to winning, and how vicious? Street fights to the knockout require a certain of individual.
An idiot.
For example, if either one has concern about hurting the other, their humanity could hamper their chances of winning. Accomplished boxers and wrestlers (athletes) would never get into a real street fight, because they know they might seriously hurt someone. In that case, the edge goes to the wrestler, as he has the capacity to control without injury. Boxing inflicts damage, and so is a lousy choice for self defense.
The best fighter for a street fight is a street fighter. That person does not care if he hurts someone, is prepared to cheat, usually starts with a sucker punch, a tackle, or a bottle to the head from behind, and will run like a coward if he faces someone trained. The police know who these people are, and the former do not care because they are in and out of jail. They are the street champs. They can have it.
If Randy Orton can take a punch then he would win most likely. All roided up in a street fight, the 15 year old dont stand a chance.
A fifteen year old who has been practicing boxing for five years and stood at 6'1 215 pounds, against Randy Orton. A WWE wrestler standing around 6'4 and 245 pounds. This question sparks my curiosity.
