Sure did, once Noll opened up the offense and let Bradshaw go to work w/ Swann and Stallworth.
Defensively, they were very good too, but not nearly as good as in '76, when they put together a brilliant 9 game stretch where they allowed a grand total of 29 points and pitched 5 shutouts. If they didn't have such a bad start to the season and had Bradshaw not gotten hurt, this team may have gone down as the best of all time.
As for which team is the best I've seen, it's either the '85 Bears or the '91 Redskins.
