I have no problem giving the Patriots credit for winning 10 in a row. You can't do that without good coaching and quality play. But neither can you do it without a healthy dose of luck, by which I mean injuries, weather, scheduling quirks (like timing of the bye and which teams you play at home and away) referee bias (yes, it exists, if only because they're human), and so on.
Put it this way: A team made up of All-Pros, with two seasons to play together can coached by any staff you wish, still might not win ten in a row. Such runs are simply not all due to how wonderful and special the team is. I'd say that if the Bills had just ripped off ten in a row. The Pats could easily--easily--have the same or worse record than the Bills and be the exact same team it is now with the exact same coaches and exact same intangibles.
So let's not get carried away by the utter gloriousness of this team, as so many commentators are. Yes, records matter, obviously, but essentially they're just another top-ten team in a season where no team in that tier has separated from the rest.
