Is Edwin Rosario the hardest hitting LW of all time?

No. Ike Williams is.

 

I personally think Edwin Rosario was the hardest puncher at 135. He was practically the Julian Jackson of Lightweight when it came to pure punching power.

 

Lew Jenkins was a terrific banger too

 

Edwin Rosario definitely had a lot of punching power and demonstrated it plenty of times. As for whether or not he’s the hardest hitting at light weight all time I’m not sure. The history of that division is very long and there were a lot of men who could bang

 

Only other hard punchers at lightweight that I think might have an argument over Edwin Rosario would be Ike Williams, Joe Gans, Lew Jenkins, Edwin Valero, Alexis Arguello, Andy Gannigan, or Gervonta Davis.

 

It's impossible to tell but for me he is.

 

Hi Buddy.
Good call on Jenkins, another Lew could punch a bit Lew Tendler , also Jose Luis Ramirez maybe.
Enjoy your posts FF , chat soon.

 

He was a monster puncher who was also a terrific fighter ... the division had its share ... Lew Jenkins was a monster .. Andy Ganigan could crack ... Joe Walcott, Chico Morales , Duran .. there were many but Edwin was a huge puncher with speed and technique ..

 

Edwin El Chapo Rosario should be included the way that he badly shook up then WBC Lightweight Champion Hector Macho Camacho on June 13 1986 in Madison Square Garden.

 

Rosarios TKO of Viruet is impressive though he fought him 5 years after Duran.

61 kos out of 128 wins, dont see Williams as the hardest puncher.

 

He's the hardest puncher I've seen there, for whatever that's worth. Harder hitter than Duran for sure. Nowhere near the fighter Duran was, but a harder puncher.

 

He turned a P4P top 3 fighter at the time Livingstone Bramble into a journeyman for the rest of his career.

I'd say hes definitely up there and no lower than top 5 of all time.

 

Rosario did hit very hard. That was sort of his claim to fame at that time.

It's probably controversial, but I would argue Shane Mosley hit harder at lightweight than Edwin Rosario.

32-0, 30 KOs. Eight Lightweight Title defenses, all by KO.

Mosley, as a prospect, sparred with reigning Super Welterweight Champ Zack Padilla and gave Padilla brain damage during their spar, forcing Padilla to retire.

Mosley was viewed as more of a boxer through the second half of his career, but he was a very big puncher at 135. And he carried much of it up to 147 and even 154 ... where he stopped champions like Antonio Margarito, Ricardo Mayorga and Fernando Vargas (twice).

Was the only guy to really stagger Floyd Mayweather badly.

Rosario wasn't much of a banger after he left 135.

 

I remember people at the time wearing signs that said "I like Ike." And there are some dummies who think it's anachronistic and about The President who boxed in the future from then and in a totally separate weight system. But I think you and me, we know it was about Williams.
