19. 2008-09 Cleveland Cavaliers
LeBron James infamously left the Cavs because he wanted to put a ring on his finger. But some would argue that the strongest regular-season team he ever played for was this edition of the Cavaliers. They went 66-16 in the regular season before crashing out in the Eastern Conference Finals to the Orlando Magic.

But that doesn’t tell the full story because the Cavaliers were excellent in 08-09. They scored points seemingly at will and had a phenomenal defense. Of the four offensive factors and four defensive factors, Cleveland ranked in the league’s top half in every single one.
