Here are some advanced stats that I compiled out of my own curiosity. The past 32 champions are listed (since that's how far back efficiency can be calculated) with their record, offensive efficiency, defensive efficiency, and efficiency differential.

Notes:
Going by the numbers, the Bulls have been by far the most dominant dynasty since 1974. The 92, 96, and 97 Bulls are the only championship teams to have double-digits in differential, with the 91 Bulls coming darn close (9.9).
How fitting is it that the two most dominant teams of the '80s ('86 BOS, '87 LAL) had the exact same eff_dif. (9.3)
The average offensive and defensive efficiency ranks of the past 32 champions are nearly identical (5.2).
Championship teams that had the best offense: 6
Championship teams that had 2nd best offense: 5
Championship teams that had 3rd best offense: 4
Championship teams that had the best defense: 5
Championship teams that had 2nd best defense: 3
Championship teams that had 3rd best defense: 4
Championship teams that had the highest eff_dif.: 14
Championship teams that had 2nd highest eff_dif.: 6
Championship teams that had 3rd highest eff_dif.: 2
Championship teams that had 4th highest eff_dif.: 6
Which means 28 of the past 32 champions had at least the 4th highest eff_dif.
