re: Mayweather says he'll give Pacquiao another shot in a year

Exactly, because there's nothing you can say.

He's done everything possible, fought everyone possible, dominated everyone except Maidana, never been knocked down, and will retire with the best unbeaten record in boxing history.

And to boot, it's been so easy for him he won't be a vegetable for the rest of his life by the time he hits 45.
