it just feels like it. But Parish did play until the mid 90s. The last great Celtic before Pierce might be Reggie Lewis?
To be fair to the Celtics, the two players that would have carried the Celtics mantle for the better part of the 90s both died while in/before their prime years of their lives. I don't think many teams have had to deal with tragedies like that in the past 20 years. To have premier players die, including one on draft night, certainly can put a damper on a franchise's swagger.
