Firstly the UFC can go **** itself. The way they used James Toney to try and denigrate boxing means that Dana and co. deserve the boxing world's contempt. Secondly this isn't a MMA vs Boxing debate. I was merely pointing out what would happen if Conor is silly/greedy enough to agree to Mayweather's terms. He would be embarrassed and knocked out if he entered a boxing ring against a top tier opponent.
Mayweather lowballed Mcgregor with a 7mil offer so he could make 100 mil. He can get better pay in the UFC so there really isn't any incentive to make this fight.
