Khan already had one fight at WW with Diaz. I have no idea why they're in such a hurry to get this signed, it could just be a rumor like a lot PBF's opponents turn out to be. I wouldn't mind seeing him wait I mean the JMM-Bradley fight is just a couple of weeks away but then again Bradley beating JMM isn't a sure thing and I'm leaning towards JMM anyway. With that said given GBP and Top Ranks history it will be hard to envision a scenario in which they do come together to get a fight made.
Mayweather-Kahn is a shitty fight hopefully Alexander-Kahn happens in Dec if either were to win in dominate fashion I wouldn't mind the winner getting the nod for the May slot, as far as the Marquez-Bradley situation I think if Bradley wins and if Mayweather is interested he'll force Top Rank to make the fight.
Of course he does; he wants a piece of that pie. This is the same Arum that blocked that whole Pac - Floyd fight. SPewed out all of those lies about the negotiations. Pushed Pac into suing Floyd. Yeah, hell will freeze over before Floyd and Bob make a fight.
