It's going to be Walker, Smart, Brown, Tatum and Theis starting. They have all earned it. They showed great chemistry and intensity in the bubble.
Most likely that leaves Tatum, Smart and Theis being the first subbed out early. Then, they will come back in once Jaylen and Kemba sit.
Thompson, Timelord, Semi, Nesmith and Pritchard most likely round out the rotation. Perhaps Langford gets into the rotation come post ASG play. Grant will, of course, see playing time if/when Semi falters.
Edwards, Green, Teague, Waters and Tacko will only see time in massive blowouts.
