Bertans guarded Durant until Pop subbed in Rudy. Then Rudy guarded him and Bertans guarded Draymond
Bertans was on Durant with Gay on the floor, and was doing a pretty damn good job untill Durant got a couple of baskets and Pop switched Gay into him. But on the very next play Gay ed up and allowed a back door to Durant that ended on and-one.

I actually like Bertans on Durant. He has the best combination of size and deceptive quickness to stay in front of Durant of all the players in our roster. Also, Bertans' main flaw on D: strength, isn't much of a problem against toothpick Durant, tbh.
