Denver has a pretty solid looking schedule so far... You really never know though about strong teams from year to year (Texans). I have a feeling that the Bengals, and possibly the Chiefs are going to suffer pretty big letdowns this coming year.
Home: Chiefs, Chargers, Raiders, Bills, Dolphins, Cardinals, 49ers, Colts
Away: Chiefs, Chargers, Raiders, Patriots, Rams, Jets, Seahawks, Bengals
I'd say they'll need to stay pretty healthy to go 13-3 again. The good thing is that 11-5 will still probably win the AFC West.
