I see Stevens leaning this way only unobviously and indirectly. That is, he frequently gives the starting bigs a quick hook, but he seldom changes the starting lineup. Sully and/or Amir could come out as early as four minutes in, at least by the second game, if needed. It would take a dramatic difference for him to start KO in the second half in some game.
Likewise, TRoz probably only gets minutes, on Schroder, after other coverages fail on him.
But Brad's a competitor and he'll get to these adjustments in a slightly roundabout and obscured way if he thinks he needs them.
