Jared Sullinger has been very impressive this preseason as he plays with the big boys. Sullinger has been playing considerable time at PF, and I believe he will sneak his way onto the starting line-up. Kevin Garnett has picked up where he left off playing center, doing well thus far, leaving the power-forward spot open in Boston. Brandon Bass is another possible suitor for the job, but Sully's looked better and has been getting more reps this preseason. The most probable starting line-up for the Celtic's in 2012 is Rajon Rondo at PG, Jason Terry/ Courtney Lee (rotating in-and-out for an injured Avery Bradley) at SG, Paul Pierce at SF, Jared Sullinger at PF, and Kevin Garnett at C.
