Well in 3-4 years these guys will be somewhat "out of their prime". I can almost guarantee that this team will look different in 3 years, as all teams chage here and there in time. I still believe the re-building process has just begun with the hiring of a new coach. It would be a huge jump to assume Musselman inherited a team full of players that he wants to go forward with.
Just as a team going in a different direction has to change coaches, a coach has to bring in the players that fit what he wants to do. That step will come. Whether that means the core players are moved. All, one, two, or none time will tell, but I see some movement as highly likely within the next year. One person I don't see being moved is Ron Artest. The Maloofs love him too much. They also have a say in things but when the time comes they will listen to Muss and Petrie and what they think is best.
