Have you even seen Shumenov fight... Judging by your posts it would appear you haven't, comparing his talent level to Gamboa. Anyway, i would say Gamboa, Dawson, Cotto (if he can learn from the loss) maybe JuanMa. Personally i think JuanMa is being over rated because of his punching power at the moment, although he is still an excellent fighter. Would love to see how he handles a top level guy who he can't knockout, and the way he adapts. Still a question mark for me.
Since when is Kessler only a p4p top 30 fighter?? Rubbish. Top 15 p4p no question. The guy has dominated a whole host of the top guys at SMW and unified in doing so, and only has one loss, a narrow one at that to the second best p4p fighter in the sport. Kessler has a far better chance of becoming the new p4p king than Shemunov... He has proven himself to be among boxings elite, in both his dominant performances against world class opposition, and in his very competitive fight with one of the best fighters p4p in the sport.
Ricardo Cordoba (hard to believe he is only 24) Abner Mares Bernabe Concepcion James Kirkland are a few 24 and unders I will be watching
Mundine, Beyer and Andrade are all world class fighters, who have competed at top level and won world titles, or in the case of Andrade been extremely competitive.
