Dom,
Absolutely, not only beat them, but knock them out. I had fighters weighing 140 pounds who hit like mules and would often drop 200 pounders. Let me say I don't recommend any fighter just starting out to get in the ring with someone 40 pounds heavier than him but sometimes you gotta do what you gotta do. There's a reason why there's weight classes in boxing.
My more experienced boxers who could bang would often times have to spar with guys much bigger because the guys in their weight classes just couldn't hang. I don't mean do bring his name up but I had a fighter "Santana D" that weighed in around 147 to 150 pounds who would knock guys out that were really good fighters 50 to 60 pounds heavier. Like I said before a fighter just starting out or a novice fighter shouldn't be in the ring with anyone more the 10 pounds out of their weight class.
Some guys have "IT" and others don't. Good luck Dom, good question.
There's no under estimating the fighting capability of a boxer, no matter small or young he is. Don't you know that a boxer's fist is considered in many countries as a dangerous weapon?
In my youth, I witnessed how a friend, barely 5-4 and barely hundred pounds, who was a budding amateur boxer knocked unconscious a big, older bully, about 5-8 and more than 140 lbs. with a well placed uppercut to the point of the chin.
A few years ago, 7-3 300 pounder Shaquille O'Neal fought a 5-7 140 pounder Shane Mosley in an exhibition boxing match. Shaq was into the contest only in the first round as Mosley mauled him the rest of the three round contest.
Rolando Navarette, the famous Bad Boy of Philippine Boxing, in his younger days also battled and beat the **** out of a lot of street thugs in Manila who were bigger and older than him.
The boxer hands down. Weight, size and height don't got **** to do with it.
Yes boxing is about technique so if u have better technique you can beat someone bigger than you
boxer 135-145lbs with a year experience age 17 and the other guy 180-200lbs but with no fighting experience age 25-30. who wins?
