He usually fights at outer range to use his reach and to avoid takedowns. He trades punishment for volume and outlasts his opponents and touts them into making mistakes. That's pretty smart for his properties. I'm not sure he's faced a kicking range threat like Pettis who has no td threat before, so I have no idea how he'd deal with an opponent like that. Also, I'd imagine Diaz might regard this as a warm-up fight for a ppv headliner money fight, so he has incentive to fight smart. He called Pettis out, so maybe he has a plan to beat him.
