You What !!
He was crap in the Mayweather fiasco - He lasted as long as Mayweather Propped him up for
As For the 2nd Diaz fight he won - A Draw would of been fairer
I can’t knock him for getting the huge paydays - if people want to pay to watch good for him
Maybe a draw in the Diaz II fight would have been fair...whatever the outcome, it was a CLOSE fight. Possibly the closest I have ever seen. But the judges called it McGregor, so he has a clean slate with Diaz now. It doesn't matter what should have been - in the record books, he has a clean slate.
As for the Mayweather fight, I would probably say that Mayweather propped him up for rounds 6-10. I think it was more of a game plan - Mayweather wanted to take McGregor into deep water that he had never been in before. In other words, he wanted him to take McGregor clearly past the 25 minute mark before doing anything. At which point, he would execute his TKO.
I do not believe Mayweather could have taken out McGregor in anything less than six rounds at the very least. He simply isn't strong enough, and he would have exhausted himself trying to take out McGregor any earlier than the 6th. Instead, he let McGregor exhaust himself, then was able to hit him at will in the 10th.
So while I would agree with you if you said Mayweather could have finished the fight in the round six, I do not think he would have been able to do so any earlier than that. And I would not say that he "propped him up" so much as he had a definite game plan, to take the fight into the later rounds before making his move. That turned out to be both intelligent and entertaining. As said, I think he could have possibly done that as early as round six, but Mayweather opted for round ten, and it worked out for him, so who is to fault him? It also made for a more entertaining fight in my opinion.
