I don't think it was only Artest. Sure he had a whole lot to do with it. Being without our 2nd option and best defender for all of 2004-2005, and a good portion of 2005-2006 (before we got Peja).
I also thing injuries was the main factor. Tinsley, when healthy is one of the best point guards in the league. And he only played 40 games this year and last year. Jermaine O'Neal is also one of the league's finest and he has only played 40-50 games the past two years. Jeff Foster is a very good rebounder and he is almost always injured also. Pollard was injured a lot also, so most of the time we never had a healthy big man.
Exact!
I would add Jonathan Bender, a big talent but he played 76 games in 3 seasons...
