I would do something like this
PG - Thomas 30, Smart 18
SG - Smart 18, Bradley 30
SF - Turner 28, Crowder 20
PF - Sullinger 24, Lee 15, Olynyk 9
C - Johnson 28, Zeller 15, Olynyk 5
Total
Smart - 36
Thomas - 30
Bradley - 30
Turner - 28
Johnson - 28
Sullinger - 24
Crowder - 20
Lee - 15
Zeller - 15
Olynyk - 14
Team clearly needs a real legit starter at center and needs to consolidate the PF's.
But why play Lee, Zeller, and Olynyk essentially 15 minutes each? Why not give the best two 22-23 mpg? Clearly, the answer isn't because of fatigue. Any in shape NBA player can play 20-25 mpg no problem.
So are we just being nice to the lesser player? If so, this isn't Little League; we aren't compelled to play anyone.
Are we trying to keep trade value up? Maybe, but how much is 15 mpg of any of those guys going to do to entice anyone to give us anything of worth?
Maybe you can argue they all have different styles, but all 3 aren't known for their defense and even Zeller who supposedly is a real center still isn't a rim protector or a post force.
So really, I'd rather just see Stevens pick the top 4 and bench th 5th. Because quite frankly, while we do have depth, we have no stars. So if Zeller/Olynyk/Lee can't crack the top 4, he has no one to blame but himself.
