Unquestionably - or at least the most accomplished. De Jesus might have been better, but I doubt it. If he was, he'd have proved it.
Strange list. Why you'd have Nelson above Williams is beyond me. I like the inclusion of Angott though, and Montgomery is a fine pick - however I think he is a bit high. I think Beau Jack was slightly more accomplished. The absence of Tony Canzoneri and in particular Barney Ross is astounding. Worst of all, Carlos Ortiz is missing. This is what mine looks like. Remember I'm rating both ability and accomplishments (which is why Whitaker or Armstrong may seem low): 1. Roberto Duran 2. Benny Leonard 3. Ike Williams 4. Barney Ross 5. Carlos Ortiz 6. Joe Gans 7. Henry Armstrong 8. Pernell Whitaker 9. Tony Canzoneri 10. Ken Buchanan -- 11. Beau Jack 12. Bob Montgomery 13. Sammy Angott 14. Lou Ambers 15. Joe Brown I know some will have problems with Chavez not being included, but he didn't accomplish as much as some of the others. He would probably be #16 if I were to rate further. Truth is, there are too many great fighters in the lightweight division. Historically it's been the richest weight class.
Arguello wasnt the boxer Buchanan was ,imo ,Vilomar Fernandez decisioned him ,and went the distance ,losing on points on another occasion.Check out Buchanan against Donato Paduano inMSG,giving weight away to a good boxer the Scot put on a boxing clinic.
I have a real soft spot for Ike Williams, so I made sure I did not overrate him. Battling Nelson is an enigma, but I like early 20th century fighters, so maybe I am guilty of overrating them. Montgomery was a superb fighter, in an amazing era for the Lightweights. Ross is a tough one; I know a lot about him, but find it hard to place him. He does well pound for pound because of his multi weight reigns. He was best at 140lbs IMO, but unluckily for him, no one cared about that in the 30s, thus he probably does get underrated at 135 and 147.
Montgomery had a better pedigree, and they were what 2-2 together? You got to love Beau Jack, but was he better Montgomery? If the answer is yes, an explanation is needed IMO.
