In 1991-92, a 35 year old Larry Bird had this season, his last:
20.2 PPG
9.6 RPG
6.8 APG
46.6% FG%
40.6% 3PT%
92.6% FT%
21.0 PER
24.6% DRP
14.4% TRP
Yes, just 45 games, but at 35 years old, that has to be the most amazing season for a Celtic since 90. There are 20 something aged stars that wish they could put up all around stats like that.
