Khan would get counterpunched to sleep inside 4 rounds. And he's an idiot - take him out of the running.
You got as much chance of seeing Mayweather -GGG than you have walking across the atlantic ocean ROFLMAO
As far as realistic fights go, I like Brook @ 147 for Undisputed. Historically I think it would be a bigger deal than Cotto, to actually totally lock down a division old-school style and be the "only" champ at WW, a premium division. With Matchroom pulling their weight in the UK, it would also be a big money fight. Not like PAC, but bigger than say Maidana/Ortiz/etc in terms of financials. Plus they are a neutral promoter whose allegiance is to Sky/UK so it can actually happen. Cotto 2 wont happen, because theres no way Al will give JayZ boxings biggest PPV platform. Just wont.
TBE has the right to fight anybody he pleases now. This last fight proved that his haters will never be pleased, so screw what they have to say. Floyd's legacy is secured 48-0 TBE
He should move up to 154 and fight GGG who has stated that he is willing to move down to 154. After beating GGG for 49-0, he should move upto 160 and fight Miguel Cotto for the lineal Middleweight title and the 50-0 record and then retire.
I can't see it not being Khan, Cotto or Pacquaio to be honest. He won't fight someone who doesn't come with a built in, proven audience. Khan has the brits and does good numbers, Cotto has the latin population and does good numbers, Pacquaio has the latin and asian population and does good numbers. While he knows he can do 800k against anyone, I think he'll look to continue getting the 1.2-1.5m he gets when he faces someone like that.
I would favour Khan or Golovkin, but I don't think that will happen. It will probably be Danny Garcia.
