Can't really be bothered to delve too far in just now but off the top of my head Floyd is at least a top 18-15 of all time - perhaps higher.
Greatest of an Era - I agree. Undefeated - Yes, but fighters have more impressive (& longer) undefeated streaks. Wins over just about every significant fighter of the era - He has a lot, but he also missed several. Best Defense Ever - No. Willie Pep. 5 Weight Division Champion - Several other fighters have done this. Top 20.
Floyd top 20 pacman top 15 Flyweight to WW is a lot more impressive than SFW to WW MAB , Erik and JMM one after the other is very impreisve even after Erik beat him. JMM was a nightmare match up for him and he fought him four times, top 15 easly
A guy deep into his thirties, still seen as the greatest in the game and we don't want to give him credit as being an ATG? What was Ali doing at 38? What about Jones Jr? or Hearns? or Leonard?
Really even better than Floyd's win over Manny?? Hmmm... I have trouble following that line of thought. Also those two (Morales and Barrera) are HOF's no doubt but they are a tad over rated. Must be the love people have for their fighting styles. People dislike Floyd's fighting style and therefore undermine his accomplishments.
He's one of the best i've ever seen really hard to rank tho since there's alot of great fighters of the past.
