I don't believe Mayweather can pass Pea either..but for the reasons I stated, he will be deserved of a place next to Pea. Isolating his greatest wins as you did wasn't necessary..I put them all into a comparative context. But the point I also included was...Juan has NO CHANCE against Mayweather, even if Juan was 160lbs and Mayweather came in at 147lbs, and Juan was memo trained and years younger. Juan has less of a chance of beating Mayweather than Nelson has on Whitaker. The domination of Mayweather on Marquez is greater than the domination on Nelson.
It definitely is underrated. He's the greatest and best H2H of the slick four: J.L.C, Casa, Corrales, Freitas.
I think this is a bit of a pointless discussion though well packaged. These 2 are amongst the most skilled ever. Mayweather is so complete whilst Whittaker is as skillful as any boxer that ever lived. Whittaker is arguably got the best defense ever and PBF is no slouch either maybe better than Whittaker offensively.
Like his second best, probably. That is comparative. The picture should be pretty clear within the top five wins, and it is here as well. I rarely go beyond that. Floyd being the worst possible stylistic matchup for Juan doesnt make that win more impressive to me than Pea moving up to 147 and beating the best welter in the world at the time, or further up to 154 and taking out a much larger beast in Vasquez. I dont care to what extent he dominated a guy who had only ever previously fought as high as 135 lbs.
