Looks like Paul George, Anthony Davis, and Rudy Gobert are popular answers.
Turner and Smart are popular bench answers.
How about:
Reggie Jackson, Jae Crowder, Paul George, Anthony Davis, Rudy Gobert
Bench:
Smart, Turner, Dudley, E. Davis, Olynyk
Monroe, Whiteside, Holiday are sneaky bench player answers. I appreciate the clever answer, though the spirit of this challenge is to choose bench players who aren't de-facto starters for their teams. That's a blurry line though. Turner plays a lot of minutes for the Celts, after all.
