Nah, I don't think so.
C - Humphries, Olynyk, Faverani
PF - Sullinger, Bass
That big man rotation looks fairly settled to me. And they have G-Wallace playing some PF minutes alongside J.Green (SF) as well. Not a lot of room for another rotation worthy big man, center, unless somebody else (a big man) is leaving to make way for the new center.
