No, I'd say definitely not. AB is a good 3&D guy but he isn't a well-rounded offensive player, and IT is awesome but he's pretty bad defensively. I'd say that the Warriors, Raptors, Clippers, Thunder, Blazers, Heat, and possibly Rockets and Bulls all have better starting backcourts. But the Celtics backcourt rotation is easily top 5, as Smart has now surpassed AB and Turner is maybe the best 4th guard in the league.
