I know some people thought McGregor would have the advantage in the clinch, being better at grappling. But grappling trying to take down your opponent is different from clinch fighting in boxing where you're trying jockey for position to punch, although there are some definite similarities. GGG trains the clinch with wrestlers for a reason. But just because you know wrestling doesn't you mean know how to apply it in boxing. McGregor probably didn't know have anybody in his camp to tell him about all the nuances of infighting. Floyd is also one of the best infighters in the game.
