There's no one guy that has to step up. Multiple guys need to step up. You're leaning on Smart + Turner to play heavy minutes at the 1 + 2, which means that Crowder is getting all his minutes at the 3. That means more minutes for our bigs. Ideal distribution of minutes imo:
Guards: IT 35 mins, Smart 25, Turner 32, Hunter 4
SF: Crowder 35, Smart 10, Turner 3
Bigs: Amir 30, Sully 30, Olynyk 20, Jerebko 16
-Don't like playing JJ 16 minutes, but I don't see an alternative. Olynyk's shoulder is still sore; even 20 may be pushing it. Amir's feet. Sully is not in good enough shape to be effective in heavy minutes.
-Can Crowder play 35 mins on his ankle? We badly need him to.
-I think we need Hunter's floor spacing more than Rozier's defense + ballhandling.
-I don't think IT can play insanely many minutes given his ultra-high-usage role in the offense, but it will be tempting to put him out there for 40 minutes, and tell him to conserve energy on defense.
