Not just statistically which can be skewed but taking everything into account - including talent and scheme.
I'd have to say the early 2000's St. Louis Rams aka The Greatest Show on Turf. I remember that team routinely putting up 40+ pts a game and just confounding defenses with all their pre-snap motions and shifts creating mismatches to the point other teams starting complaining about it. Then the personnel - the speed they had at receiver from Isaac Bruce, Tory Holt and Az Akim and how dangerous they were in space. Then there was Marshall Faulk who was such a deadly weapon as a runner and a receiver. Then of course the Cinderella story that was Kurt Warner who still owns the record for most passing yards in a superbowl.
If you love offense (like me) that was the team to watch.
