The more I think about it, the more I think that white is better suited playing on the bench, as the 6th man. DDR can be the primary ball handler and Murray can be the secondary ball handler in the SL.
Forbes is better suited playing alongside them because he is a higher volume shooter and better than White shooting the 3, making him more ideal playing off the ball.
Byrn can start and play the first seven minutes of each half; White can then play the final five minutes of the first and third quarter and the first four minutes of the second and fourth quarter, then come back in and close each half after a few minutes on the bench.
In that scenario, White would have about 12 minutes per game to be the primary ball handler in units with likely Mills, Beli, Bertans, and Poeltl.
