I'm surprised Olynk isn't an option here. To me it really comes down to he and Humphries. That decision will tell us a lot about our goals this season too because Humphries is probably the win now option.
If Olynyk is in the game in favor of Humphries, then the center will actually be Sully.
Why do you say that? And wouldn't that be more or less predicated on the matchup?
What he's saying makes sense though.
The 'PF' vs 'Center' distinction is a bit dubious in the modern NBA.
What is more relevant for most teams is 'stretch' versus 'low-post'.
If Olynyk is in the game, he is going to play 'stretch big'. Whether you want to call him the PF or the Center is irrelevant.
And if Hump is not in the game, (i.e., Olynyk being in the game 'in favor' of him) with Olynyk, then Sully is a likely low-post complement for him.
Whether you want to call them centers or power forwards, we have bigs that can play the two roles:
Stretch: Olynyk, Sully, Fav, Bass
Low post: Sully, Hump, Olynyk, Fav, Fab
Faverani is not quite as good an outside shooter as Olynyk, Sully or Bass, but he can start his offense from the outside with P&R and P&P.
