Not sure if this has been talked about in this thread, but here goes:
I watched the end of the Dallas vs. OKC game last night. Westbrook took over down the stretch. Handled the ball on every possession and either scored or assisted on nearly every damn possession. Ball-dominant, but dominant nonetheless. I'm sure we'll see Neto on him in the early going. If we close with the 3-wing lineup, I'm not sure who can slow him down. I think Hayward is the best defender of the three, so I'd hope it's him. Something tells me it won't be, though.
