Keep AD healthy, that is their key to win every game. Rest him if they think their opponent can be handled by the other players.
Make him the VIP of the team as it is a fact that he is the only one who could bring them more wins than any players. Yes, that includes Lebron and Westbrook.
Yes, they should at least give Davis some rest if they will be facing a much easier opponent or an opponent that they seem they can defeat without getting Davis plenty minutes. The other guys could handle that kind of scenario given that Westbrook is also getting a hold of his new role and LeBron is still remarkable contributing decent numbers per game, and well, they also got Walker and Reaves for that job.
The last two names stated needs a lot more exposures so that they will be much more reliable when the game becomes more intense before the qualifiers, they are good now but the team needed an improvement because time will come that Davis and Lebron's numbers won't guarantee to keep them afloat.
