This is just stupid and fan should stop being stupid. There is noway for floyd to make 160 or anywhere above 155 and still function .. Floyd is small framed 5'8 fighter , it would be different if he were a large framed fighter. 150 is already above his max how does he compete at 160 and stand a chance against any of those fighters entering the ring at 180 ? Sparring a guy at 180 is one thing fighting a guy at 180 is another.
Floyd could enter the ring in the low 150s and still beat nearly all of the current MWs. In his prime (now past) he could have beaten all of them except Martinez.
I wouldn't even blame or criticize Floyd if he chose not to fight a guy who comes in at +170lbs on fight night. Yes, the widely accepted notion that he has not done all he can to make certain fights, or for lack of a better phrase "ducked fighters" will be substantiated, BUT I'm not gonna blame a fighter for not taking an extremely tough fight at this point in his career, when he is just 1 fight into his final 6 fight career deal. However, if the fight does happen and he genuinely wants to prove himself against the best... 154lbs
