I want the Celtics to have a team modeled after the 2002 Sacramento Kings.
That is a team that anyone can root for. They were always one of my favorite teams of all time. I'm watching them on NBA TV right now, and although I always remembered liking them, watching them is a true experience. If we want a team with parity, I think we could go after this exciting model that is not unlike the Spurs of this year.
http://youtu.be/vglV2qpoD70I know that the Celtics have very few similarities to the 2002 Kings at the moment. Reality be darned, though, I would love another team in this mold. Solid fundamentals, pushing the ball, ball movement, pick and roll, off-ball cuts, all very simple things that are beautiful when put together.
EDIT: On another note, I think Adelman is one of the most underrated coaches of all time and definitely a HOFer.
