On account of most TDs scored in a single season. Or maybe that they got the most passing yards in a season, ever. Or maybe that it is 4 receivers have at least 10 TDs, another first. Longest FG. Denver got that as well. Oh wait. Maybe it is most poitns scored in a season. Or maybe it was the most passing first downs in a single season. Or maybe it was that they have scored the most points in the second half in a single season. Oh no! I know!!! It was that they tied the record for the most 50 point games in a season (not the 49ers btw). Or maybe it was that Prater was 75-75 on extra points this season (including playoffs).
I didn't include any franchise or player records. Just the league records. Player and franchise records get into TDs by a TE, sacks allowed, FG%, 50+ yard FGs, interception percentage (career), passer rating, RB with 1,00 rushing and 500 receiving yards, first downs, points in a game...
It is no stretch to say that Denver has the best O off all time. I can see people arguing for other teams but don't discredit this Broncos O. It is historic.
As far as teams with total sacks. Danver has faced the #s 2, 3, 6, 7, 10, 14 & 15 ranked teams. Denver themselves are ranked #10 (tied with 3 other teams). Seattle is #19, very middle of the pack. Perhaps Wilson should be more worried than Denver.
