Plus Kawhi is already a better lock down defender than Marion ever was........Matrix has never even made a single All-NBA defense team in his career. Dude was a very versatile defender but I've seen everyone from Dirk to Manu put up career numbers on him in the playoffs. (Tyson Chandler was the anchor of the Mavs defense when they won their rental chip....which is why the bottom fell out once they let him go even though Matrix was still on the roster)
