Delonte was kinda their second best player... they will improve when he comes back
That would be very sad if it were true. He'd be the.... 8th? 9th? best player on the celtics.
You know what? You're right...even though I think Mo Williams is better than Delonte, and i think DWest would be better than Quisy which would put him 7th on our squad. LeBron needs some help. I sure hope he doesnt get any until weve won at least 2 or 3 more titles. 
Uh, no. Delonte is a better shooter, I'll give him that, but a better player than Marquis? I don't think so.
I would say they are at least even without Delonte's current baggage. When Delonte is on his game with no distractions, he is very effective offensively and defensively.
Delonte: Better shooter, equal defensively, equal passing
Quis: Better slasher/ finisher, equal defensively, equal passing
