If we're being fair, which you clearly have no desire to do, the only wins that matter in this comparison are SF and Indy and Indy was hardly an elite team that year. They were very good, and Peyton Manning-led teams are always dangerous, but Indy lost in the wild card that year and when we beat them, that was their third consecutive loss.
The Philly-Cincy-Pitt streak was nice, but only one of those teams finished the season with a winning record. None of them were elite by any stretch of the imagination. How is that anymore impressive than Philly winning 5 straight last year, including wins over 10-6 Arizona and a win in Lambeau?
