Yes, they waited until the Super Bowl against the Giants to rest
Seriously, this conversation comes up every year, and it never gets any less dumb. IT'S BEEN FOUR GAMES, PEOPLE! You know who was 4-0 at this time last year? The Cardinals!
We don't know if the Broncos are going to go 16-0, we don't know if Peyton's going to challenge the record, we don't know how good the rest of the conference is going to be, and we certainly don't know if it's going to snow on a random Sunday in December (it's Denver, not Siberia).
