They'll share minutes in the second unit and duke it out which is a good thing. If the question is who will get the most minutes, I think it will be 50/50 until the RRT................................. and then either Lonnie has broken through (which I think he will) or he hasn't.
Probably.
For 10 minutes a game? Yeah, let's take the ball out of the hands of our most crafty player that has natural PG skills to put it in the hands of a low IQ guy with a high dribble.
White needs to have the ball in his hands a lot more than Murray. Even DeRozan should.
Unless at least one of Murray or White has made a quantum leap from 3, they'll probably mostly split the PG minutes, with White probably generally closing.
The reason they'd bring White off the bench in that scenario, is the fact that he'd obviously have a more featured role with the bench, where his superior play making is more needed.
But if White is ready for a Siakam like breakout, then what? They're not good enough to play politics, so it's either start him at SG, sub at the under 6 in the 1st and 3rd, then alternate him and Murray ala Aldridge and Gasol (this likely requires running a 9 man rotation) . . . or trade DeRozan.
