Based on the Observation of the team the last 2 years, i'll say this...
Our Starters base there game off Great Defense which leads to Punishing Offense.
Our Bench are no match for other team starters on the defensive end, and other teams bench except for ours have that 1 scorer that we usually call the "Celtic Killa". Im the past Doc has tried to make Tony Allen the offensive initiator off the bench but Tony's inconsistent, out of control, isn't a creator for others, and he can't shoot. He's best at lurking the passing lanes deflecting passes.
Our Bench in 2008 had a great offensive combination of Posey, House, Scal, Baby, Powe, and PJ. They're all good @ what they do offensively that their offense became their defense. The team struggled miserably this year because of our offense. Rondo's Reluctance, and the Bench limited/inexperience.
