Law isn't going anywhere. I am predicting that he will be ROY.
I'm really not a big Law guy. He's too limited physically. He's going to be a defensive problem too. If you really want to run Smith at PF, and Marvin at the same time, you have to run, and Law isn't a PG who can run. They need a pace setter type of guy. Calderon or Lowry would both fit better IMO.
I have come around a little bit on the Law fit. If you let JJ do most of the execution stuff, Law is a very good shooter off of that sort of stuff. He's got a tough mentality. He reminds me a little Derrick Fisher. But I'd still rather see them with a pace car running the show.
But good luck anyway.
