The Jazz need to make a few business decisions. If they want to maximize Rudy, then Joe has to initiate the offense more and Conley needs to play off the ball more. But that means Conley doesn't get in a rhythm like he did last night.
If the Jazz want Clarkson to carry a scoring load with the 2nd unit, then it's more important to pair him with a PF who is a 2-way player, rather than a pure shooting specialist like Niang. And since Clarkson is a limited defender, the Jazz have to compensate by playing him with an athletic wing and center who do play solid defense.
