Who would you add ? Of the top of my head im thinking Bradley - Khan. I would also add Gamboa there and Canelo against someone at middleweight to set up JCC fight.
5 fights: canelo vs chavez jr maidana vs matthysse cotto vs martinez 157 khan vs bradley donaire vs gamboa 126
I was going for something like this but Gamboa would have to move up and fight Gamboa as his first opponent as Featherweight and the same goes for Canelo. I would also make Pirog - Martinez instead of Cotto.
Also what about Marquez - Rios instead of Maidana. Also if there was any famous boxer in China or something would be epic China buying would be a lot of cash i would think.
With respect to symmetry, and of course each of the involved promoters will certainly vie to showcase one of their fighters in each televised slot, I matched a GB fighter against a TR fighter: Khan-Bradley John-Gamboa Mares-Donaire
Manny Pacquiao-Floyd Mayweather Brandon Rios-Marcos Maidana Lucian Bute-Andre Ward TImothy Bradley-Amir Khan Canelo Alvarez-Alfredo Angulo HELL YEA!
