Which boxer in their prime would never lose to another fighter?

Don't be mad but Mayweather runs through Duran, Leonard, Hearns, Hagler, Whitaker, and Chavez Sr. Well not Hagler, but the rest. You've got yourself confused. He'd have 'ran away from' not 'run through'

Since I started watching boxing, RJJ is the single greatest boxer I have witnessed. I believe he is the best fighter since SRR. FMJ is the best since RJJ, but I can't say that FMJ would beat all of the greats of the past. Anyway, the answer is RJJ. Soon, it will be RJJ and Lomachenko.

No actually. Not when you're stupid enough to post this. Do realize we're talking in a HISTORICAL CONTEXT. I'm comparing prime 140lb Pacquiao vs. all of the other 140lb greats from history, and I believe he has a shot against all. What the **** don't you understand? Only other fighters I can name would be Lewis at HW & RJJ at LHW. Let me dumb it down a little more for a brainless cotton picker like you. Prime Pacquiao at 140 could beat all other 140lbers in history. Prime Jones at 175 could beat all other 175lbers in history. Prime Lewis could beat all other HW's in history.

Don't be mad but Mayweather runs through Duran, Leonard, Hearns, Hagler, Whitaker, and Chavez Sr. Well not Hagler, but the rest. Sugar Ray Robinson?

Well I'd have to say no one because any fighter would have met his match if his opponent was also in his prime.. that said, the greats make adjustments and come back strong in rematches.. The reason Ali is ranked way up because he faced best HW guys in their prime...

.... Prime 2008 Pacquiao vs. Prime 1992 Whittaker. Or Prime 2003 Tszyu. Get the idea, prick? No actually. Not when you're stupid enough to post this. I'd say Pacquiao if he stuck at 140. Great fights with Tszyu, Chavez, Mayweather, Whittaker, & Crawford to be had.

You're apparently too stupid to understand timelines. .... Prime 2008 Pacquiao vs. Prime 1992 Whittaker. Or Prime 2003 Tszyu. Get the idea, prick?

In and out of prime, Floyd.

I'd say Pacquiao if he stuck at 140. Great fights with Tszyu, Chavez, Mayweather, Whittaker, & Crawford to be had. You're apparently too stupid to understand timelines.

this idiot just illustrated my point. ROFL. Hearns, Leonard, Hagler never fought at 140. Everybody else on that list, Pacquiao could possibly beat prime for prime at 140. 140.

I'm inclined to say Roy Jones Jr as well

We just had one Floyd.

We just had one Floyd.

Ali was better in the 70's than the 60's. I know you will argue this but even ali admitted he was stronger and a more placement puncher with better ring IQ and thats because he was. Ali was lucky on two occasions in the 60's by far less fighters. Wow this is dumb, a blind man and his dog knows alis prime is the latter of the 60's he was sharp and moved unlike anything the heavyweight division had or has ever seen and still had the same chin,his weakness in some fights was toying with fighters and giving them chances like cooper A ready and focused ali like the one that fought listen beats every heavyweight thats ever exsisted

Adrian broner at lightweight,did you see the way he toyed with the mighty rock know as gavin rees

No prime boxer in history could remain undefeated against every opponent....if they fought all the competition that was available to them. If a boxer fights often enough, he WILL be defeated. The level of talent and ability amongst fighters at the very top level of the sport is very minimal. The assumption that anyone in invincible is completely ridiculous. Even if an all time great boxer was fighting tomato cans he would eventually get hit by something that would stop him or he would run into a mediocre talent that had immense tenacity, toughness and will power.....Boxers are humans, not machines and definitely NOT super heroes.

Wlad from 2006-2012 would beat any heavyweight hit Klitschko on the chin, and he still folds over, regardless of the year you point out.

RJJ, Roberto Duran from first SRL fight was too much for anyone

I'm one of Roy's biggest fans, but you've exaggerated. lol, and more than a little bit. :boxing:
