The Celtics always take pride in the fact that they have never produced an NBA scoring champion. In truth, they’ve never been big on any kind of individual achievement honor unless, of course, it’s the Sixth Man Award. That means something because, well, Red Auerbach basically coined the concept. The Celtics have had three of those. But they’ve never had a scoring champion — and that goes all the way back to 1946-47. There has been no rebounding leader since 1965 (Bill Russell). There has never been a blocked shots leader.
