I get what your saying Boxbuzz, and although I believe Whitaker was the greatest lightweight of all time, totally respect anyones opinion that Duran was.Duran's combination of talent, skill, durabilty and will puts him at the top of the lightweight division all time IMHO. That does not mean to say that he tops every catagory. When it comes to pure skill I think one can reasonably make the claim that Pernell may top the list. But based on our assessments, or impressions if you will, it helps sort out why you think Duran would not be competitive with McCallum.
I can't quite remember your take on Tommy but in order to glorify Tommy at Duran's expense one has to sort of put Barkley in his place. (Or vice versa if you think Duran has credibility at the higher weights)...two very popular landscape scenarios here at boxrec, from what I have read. Now some people do not use that construct...and I can not remember where you stand, I was just throwing out keys to popular scenarios. Not sure if you even fit into those catagories. I find the McCallum Hearns, Duran fights too close to call. Oh and I'm sort of a "no excuse" person so the Moore thing doenst carry a lot of weight.
The 3 way go round of Duran, Hearns and Barkly does make for interesting prediction patterns however. Styles do make fights but a loss is a loss and a win a win in my mind. No excuses for Cerdan, none for Duran, none for Moore.
But that has nothing to do with why I believe McCallum would beat him at 154. I just dont think Duran was good enough at that weight to deal with the body snatcher.
As for Barkley, I believe he was fortunate to face Hearns after Hagler fought him. It was evident after the fight, especially against Roldan, that Hearns chin never fully recovered from the battering Hagler gave it.
Barkley fought in the perfect awkward style to take advantage of that.
As for my take on Hearns, besides Robinson Leonard and maybe Armstrong, no fighter south of middleweight in history would have beat him.
