Over the course of the first three games of this series, I don't think it's any stretch to say he has been the Cavs best player on both ends. LBJ was awesome in games one and two...Kyrie was awesome in games two and three. Love has been great in all the games.
His defense has just been incredible. He is moving around like an agile big out there. Showing and recovering, switching when necessary, contesting shots when asked to guard post ups and isos, and making multiple efforts. And as always the most underrated part of defense is defensive rebounding and Love has been great at that his whole career.
