Demian Maia is a sub master on the ground. But he'll have a lot of trouble getting Rory MacDonald there in their fight. So, it's a stand up fight mostly, and that's good news for Rory. He has the better striking and will win this fight via decision. He doesn't want to play around with Maia on the ground, so will pick him apart on the feet and avoid the floor. He'll take at least two of three rounds.
