Starters in bold:
PG - Rondo, Pressey <starts the season at PG until Rondo gets back
SG - Bradley, Lee, Brooks, Crawford
SF - Green, Wallace, Bogans
PF - Olynyk, Bass
C - Sullinger, Faverani, Humphries
Assuming Rondo isn't ready to start the season than Bradley could get the nod, though if everything goes great Pressey will impress in camp and take the starting PG job until Rondo gets back. Also I have high hopes for Faverani taking the center position and rolling with it as well as Brooks maturing enough to take over the shooting guard position, I readily admit that this paragraph is wild eye'd, pie in the sky thinking and I'm projecting upward but I have a lot of faith in Danny Ainge's ability to spot talent.
Assuming this ^ fantasy scenario happens and everything goes right, the starting five of the future would be: Rondo, Brooks, Green, Olynyk and Vitor. People will ask what about Sully, I have deep concerns about his back being able to handle a starting load over the course of a season and he could be very effective as a 6th man. There is also the distinct possibility that once Rondo returns and proves he is healthy and Pressey has already shown he can start Rondo will be a trading chip. In that case swap out Rondo for Pressey above...
