Found this website trying to find head to head wins for Denver vs New England to shut up some ChowdaHead trying to give me the business on a Browns forum. Hahaha, isn't that funny. He said the Pats own the Broncos all time, of course I had to point out, thanks to this website, the Broncos OWN the Pats all time 27 - 19.
But anyway, you can get almost any NFL data you could think of at this website. Box scores from 30 years ago, superbowl winners, coaches stats, player stats, head to head matchups, whatever you want, it's there.
