No. 1: 1985-86

Record: 67-15
Playoff record: 15-3
Result: Championship
Bird was at his peak. The greatest team ever if you consider no other club has ever brought anything resembling a healthy Bill Walton off the bench. This squad was 50-1 at home, regular season and playoffs combined. This Lost Generation of Celtics fans need no longer slap on their headphones and begin rolling their eyes when the smug followers of champions 1 through 16 begin rhapsodizing about the virtues of their favorite Celtics squads of yore. Their team, No. 17, can compete with any that has ever worn the Green and White.
