I think Morris would be starting if he were here but since he is not, why not let Yabusele and/or Theis get minutes so we have a chance to see what we have. Baynes is much more of a known quantity so other than getting reps with the new system, there is not as much learn about him.
I like starting Smart also, again, let's see how he looks alongside Irving and the other starters. Then let Brown, Rozier, Tatum, Larkin run as a young group.
