The only player I can really think that would immediately fit next to Westbrook would be Klay Thompson. He'd be ideal for Russ in that he plays off the ball and he defends at a high level, both guard positions.
After that I feel like he would have meshing issues with lots of players.
Klay Thompson fits with anybody.
I would load up on 3 and D guys who are secondary scorers and are good without the ball. Klay, Middleton and Ariza come to mind right away. Covington would be good too.
I think you need a skilled big like Horford, and a defense first banger like Adams also. Sometimes you go big with both, sometimes you go super small depending on matchups.
I do not think this would be an easy exercise though. Russ is tough to play with.
