You guys are all getting caught up on the wrong thing! Instead, think of it this way:
Last year Rasheed Wallace hoped to not have a crappy season with the change of coach, players, etc.
THIS season he's extremely optimistic, is buying the kool-aid, and is immensely buying into the team and players around him.
They really do believe they can go out and win every single night. THAT is the kind of optimism and night-in night-out attitude I want the Celtics to display. And this particular thinking is not going to exhaust the players so they can't play in the playoffs.
