I think Olynyk will have to earn his minutes back. This team is playing much better ball without KO and the last thing Stevens wants to do is lose the locker room by GIVING minutes to a player over players that have performed better overall than KO, especially while the team has garnered some success.
Not saying KO can't win back the playing time, but just to hand him back a starting spot or a rotational spot with 24 MPG over Bass, Sully, Humphries or Fav when they have been playing well and contributing to wins, goes against what I think would be good for the locker room and instilling a winning environment.
He doesn't belong in the D-League.
