I've never really put much into the "strength of schedule".
Teams will change, players will get hurt.
But what's really important is taking care of the division. The rest of the division has to play many of those same teams. A couple years ago, Oakland went 6-0 in the division but missed the playoffs, but that was a huge anomaly.
Take care of the division, the rest will sort itself out. Look at the Giants this year. Didn't have a great regular season record, but won the division. Once your in, anything can happen.
It will be a brutal schedule, but it will for the rest of the AFC West as well.
