Hey man, I have no beef with you and I really enjoy the back-and-forth discussion that has been going on in this thread (the rest of the board seems dead).
Anyways, I agree with your point that if the Celts want to make a serious run at the title, than winning Game 6 will probably be their best course of action. They could most certainly use the rest.
As for the other argument, again, it was just for the purposes of discussion. No one was trying to get anyone else riled up. If you want to call Allen, Pierce, and Garnett career losers just because they haven't won anything, that's your call. I simply voiced my opinion why I think you're wrong and that you underestimate the value of role players surrounding these superstars.
I think the discussion was relevant because there's been lots of rumblings here in the Northeast about the very thing you posited - IE Garnett, Pierce, and Allen are "career losers" or "phonies" because they are having such issues in the playoffs.
