He needs to, otherwise he won't have a reasonable excuse for getting schooled. I think he may not make it though, maybe I just hope he won't so the Floyd haters will have to scramble for another reason why Floyd wins.
I hope he says **** it and comes in at 154 and pays the fine. It'd make the fight more interesting and Mayweather can hardly take the moral high ground. I doubt he will though. He will probably make 152
