Not completely. I'd say its still guard wing big, although Green and Williams are straddling either side of wing. OTOH, it does feel that way, and I suspect it is driving Doc crazy.
Doc is a system coach and he's going to insist on sticking with that, defensively. To his credit he's left the "freedom offence" in place since Rondo went down and it seems to work, so far.
I do wonder what, if anything, Doc and Rondo are learning from all this. I wonder if Doc is seeing Twill as a Rondo lite, and will try to revert to PG centric offence.
