I did hear him saying something about. Made some remark about how they only fight 5 rounds or something like that. If he took the beating the UFC guys did he would see why they dont go 12 rounds, they never last that long anyway! I would love to see mayweather step in the ring with a UFC guy, he would have an eye opening experience for sure. The other big difference, is boxers wear 16 ounce gloves, the UFC guys wear 4 ounce knuckle guards, mayweather likes to talk be he'd be stupid to try.
