No need for Conor McGregor and Floyd Mayweather to duke it out in the ring ... 'cause hip-hop legend Warren G says the outcome would be a beatdown ... and Money Mayweather would do the beating.
We got Warren -- a huge boxing fan -- out in L.A. and asked him about the hypothetical fight EVERYONE is talking about, Conor McGregor vs. Floyd Mayweather ... basically, who would win?
Add Warren to the group that doesn't think it'd be much of a fight .
