I'm incline to say Yes.
I think Nick hits harder than Nate, has better wrestling, a better chin.
Basically just a little bit better at everything. He was a Strikeforce Champ and Fought GSP.
If it had been the Diaz Trilogy against Conor, i think Nick would have wasted him both times.
By knockout though, not submission.
He might have ended all the Conor hype right then and there, before he even got to Mayweather.
saying you hit harder than nate isnt saying much cause either guy is a power striker.
there was no way nick would taken the fight on 10 days notice i think he was still dealing with the whole usada thing.
