I wouldn't underestimate Mcgregor on this one. He can take a hell of a hit. Mayweather is good but he has to prove to me he's worth it after that Vegas fight he had that I was interested in and they basically ran around the ring and didn't do any fighting. Mcgregor won't back down so at least there will be a fight this time. Never underestimate anyone from the UFC, their a more technical fighter so fighting like a boxer will tire them out but some of them have a standing style and Mcgregor is good on his feet.
