Mayweather is too big, fast and smart for Pac.
Pac is good but May is better
you have a 3 maybe 4 round window fighting May if you cant beat him by that then you're done.
Mosely screwed up by just looking for the big punch after the second round. May is too smart for that and will not let you catch him slippin again. He knew what Mosely wanted to do and he had the perfect counter for it.
