McGregor's ground game still couldn't hold Nate's jock in a suitcase. Diaz is a very skilled boxer, enough of a reach to keep McGregor at bay. I'd put it at 3 to 1 odds that Diaz wins by either decision or submission again. McGregor would have to land a surprise shot on Diaz, and even with that, Diaz's ability to recover and grapple could marginalize its effectiveness. Just my two cents.
