Nate "won one for the fighters". How would it have been good for Nate if Jose Aldo "won one for the fighters"? It's not good for the hugely diminished payday you're going to get when you face a defeated McGregor. It's not good for the promotion or the sport in general.
A rising tide lifts all boats, and everybody's pay goes up when people like Brock, Ronda, and Conor are creating huge buzz.
If you could make a change in MMA, what would it be? Would you take the matchmaking and marketing power from the UFC and give it to the Athletic Commissions? Would you implement something like the boxing model?
