Assuming we're able to pull a three-way for Dalembert and Chandler (using Sweets, Jamal, Penny's expiring deal and some picks) and then trade TT's contract for Marion in Feb, this would be my happily-capped lineup:
C - Dalembert
PF - Chandler
SF - Marion
SG - QRich
PG - Marbury
Bench:
Nate
Ariza
Lee
Frye
Jerome James
Jackie Butler
Mo Taylor
IR - Allan Houston
(waive Malik Rose)
If we can't get both Dalembert and Chandler, then I would start Mo Taylor at PF because he's a monster posting up and that would give us a better insideout game.
