Floyd is the WBC Champ, Devon Alexander is the IBF Champ, Timothy Bradley is the WBO Champ, and Broner is the WBA Champ.
Floyd: He will not fight Broner (so he says right now). Tim Bradley is with TR and Floyd wont deal with Arum. Alexander is the only one he would fight, but Alexander isnt a draw, and Floyd isnt interested in fighting non-draws
Alexander: Him and Broner say they are brothers and wont fight. Bradley is now with TR and and GB doesnt deal with Arum anymore. He could fight Floyd, but he isnt a big enough star and Floyd doesnt fight non-draws
Bradley: He is with TR and every other champ is a GB fighter. TR and GB do not do business together
Broner: Floyd and Alexander are his "brothers". They will not fight each other. Bradley is with TR and Broner is with GB.....they will not fight bc of promoter issues.
