I like McGregor, but he got full of himself. There are weight divisions for a reason. A skilled big man will beat a skilled small man 9.999 times out of 10.
It's just simple physics.
Diaz may have looked flabby, but he fights at a heavier weight. And he can box and has an excellent ground game, unlike Connor.
Connor is going to have to develop a ground game if he's going to fight in the heavier divisions - and I don't know how possible that is.
It's probably good that Connor loss. Rumor has it he was slated to fight Robbie Lawler if he had beaten Diaz. And Robbie would have destroyed him.
And, LOL, on Aldo talking smack about Connor. Uh, dude. You got destroyed by Connor in under 20 seconds. You'd best shut up until you get a rematch - if you ever do.
