McGregor's trash talking gets a bit too much. Betting Nate can't count to 5, skinny fat dude, " I am going to toy with him and then Knock him out with an uppercut in the first round, etc....
For that, Nate should have let him up and punished him slowly. Think about the attention Nate would have got if instead of choking him out, he let him up and then flipped him off and then proceeded to "toy" with him while citing all the shit McGregor said.
