Monty Williams needs to figure out something with Booker, he can't let Beverley dictate that match-up as it is. Particularly, don't know how you can keep having Booker running your plays and bringing up the ball with Beverley up on him.
I'm sure the mask also is playing a bit into his discomfort, in this particular game, but Beverley has his number and I don't see Monty doing any adjustment for it.
