I don't understand Mayweather Jr.

Why make all these demands? All these random blood testing nonsense. I mean, I'm not a big fan of the guy, but I believe him when he says Pac will be an "easy" fight. Why not just fight him, you know. Beat Pac, make your $40M, and add another feather in your cap. Now the fight is on the verge of being called off and he's about to lose out on millions of money that he desperately needs. I don't understand his intentions at all. I know for a fact that he's not afraid of Pac. I mean damn, he already has all the advantages. He's physically bigger, taller, longer and has better overall skills. Just a dumb move on his part if he misses out on this "easy" payday.
