Barry will get his playing time when playoffs start because he is the only player on this team with a lot of playoff experience, besides Artest when he was in Indiana. He is also a older player, so Adelman will limit his minutes during the season to avoid injuries.
Classic post for someone unskilled at watching basketball. Hint: Go back and watch how much more efficient the team is (espocially in transition) with Barry over Head. You just might learn something about the game.
