Jack Sharkey vs Johnny_B

As far as I know (correct me if I'm wrong), nobody has measured his punching power (and most boxing champs) in a scientific manner, therefore I cannot give you a definitive answer. But I'm inclined to say I hit just as hard, if not harder.
Punching power is determined by 3 major factors: speed, mass and technique. I'm probably as fast as he was, if not faster (based on the footage I've seen of him), I have more mass to put behind my punch and my punching technique is very good since I've been developing my fundamentals since I was a kid.
But punching harder than someone is not the same with beating him. You need more than just punching power.
David Tua is the best example of this. Could hit like a mule, but lacked in other departments.
To sum things up, in the HW division, most good pros pack 1 punch KO power, the problem is they aren't able to use it effectively.

 

The way you were talking I figured you were 6'10 and 280 or something.

 

If those fighters are of similar size to mine, or close, sure, they might just do that. But someone like Pacquaio or Mayweather won't be able to beat me even if we fight a million times, they're far too small.

 

Assuming you are correct, then he'd beat me. But I'm confident my hand speed is more than enough to land.

 

A bit of footage and a few good credible names and I'd make Johnny_B a live underdog at least.
Just waiting on some names and some footage.

 

I wouldn’t bet against them. I used to do some boxing and I know there are guys and gals that can bang at lower weights even if you know how to use your height n weight. And if you are as good as you claim you should post some footage and be proud! Most guys here have boxes at some point in their lives for fun or professionally

 

I train 2-3 times a week with a couple of friends and some other guys at a local gym. We spar once a week, but we use headgear and try not to hurt each other. Like I've mentioned and you all know, taking shots to the head is not good for one's health, as we've seen with countless pro boxers. I've also sparred with guys from other areas (friendly contests).
I come out on top in most cases, but if I look at things objectively, it has more to do with me being in great physical shape and having over 20 years experience than it has to do with talent. Basically, if you practice the same thing a million times, you get good at it.

 

Have you taken part in official amateur competitions ?
Have you won trophies ?

 

At 280, I'd be a fat bloob practice target, they couldn't miss me even if they wanted to
God forbid I'll ever become that big/fat.

 

Yes, as a kid, from the age of 14 up until the age of 16, when my uncle died.
I stopped after that. I won 3rd place at the age of 15 in a local amateur event. I got beat by the guy that would go on to win the event, he was far more skilled than me, I had no chance whatsoever. The guy I beat for 3rd place was also a bit more skilled, but I managed to land a big punch that knocked him flat on his back and made his nose bleed. It was more of a lucky punch, but I was very proud of myself back then.
I've sparred with many good amateurs (and done very well) since, but it was just friendly sparring, nothing official. As I've said, I decided a long time ago not to see/take the sport as a profession. It's just a passion/hobby for me, but which I take seriously by training regularly and trying to improve all the time.

 

I thought he weighed no more than 185, 190 at best.

 

So what makes you think you've become good enough to beat world class professional welterweights or middleweights ?

From what I'm reading, you've developed relatively great skills at friendly spars with some guys who you think are good at sparring. You've been doing it for many years and know some tricks at friendly sparring, and you're in shape, big and fast. Okay.

With all due respect, being "good" at what you do is a far cry from being good at hard professional or high level amateur sparring, or good at actual amateur competition, nevermind good at actual competitive pro-style fighting.

A guy like Floyd Mayweather, even with big gloves and headgear, would likely tear your ****ing head off without even breaking a sweat. You'd have no chance of landing an effective punch.

There are levels to this game, bro.
