Sb is often mentioned, but mostly from dudes who didn't play it. As for me it work without it, maybe it would work better with it.
Special at my roster is, that i had several big with "relativ" high OD(8-11) who also get some minutes at SF, so maybe decent OD for the player is a key or good ID and Reb on SF or a combination of it ;) This season i played it less, and have also lost some OD in my frontcourt.
