For one, I think it's tragic that Pistol Pete finished his career w/o a ring, however, unlike Bob MacAdoo, he wasn't despised by the Celtics management (i.e. Red and Co).
Would it have been better if Pete had ridden the pine, during the '81 season so that he could go out with a ring on his mantle? And even better, a ring with the Boston Celtics, his final stint in the league.
Now, he's on that infamous list with Baylor, Barkley, and Ewing of the great players who never won a title. At least MacAdoo got to ride the pine with the Lakers for a title.
