With a backup pg in Rozier now, I could see IT starting and moving Smart to SG, making Bradley available or Brad wanting Bradley to be the scorer of the 2nd unit. I prefer the former by pairing him with one of our younger bugs to possibly upgrade our wing position.
Though, this depth chart might make more sense for us:
PG: IT, Rozier
SG: Smart, Bradley
SF: Crowder, Turner
PF: Lee, Sully, JJ
C: Johnson, Zeller, KO
