Some points:
1. New head coaches in Denver (no Wade Phillips coaching the Denver D as well), LA Rams, San Francisco, and the LA Chargers.
2. Aging QB's for Arizona & the Chargers, Denver has no QB, and a lackluster Alex Smith with the Chiefs.
3. Dallas will be better prepared to play the Gnats (Eli can easily be rattled).
4. Seattle outside of Seattle is a definitely a winnable game.
Basically, Aaron Rodgers is the only QB who has consistently scorched Dallas.
Wentz, Carr, Cousins, and Ryan can all be corralled, and knocked around if Marinelli develops an aggressive defensive scheme.
Dig deeper that schedule is not that difficult ~ assuming Garrett does not get out-coached (Andy Reid or Mike McCarthy will be a challenge) or fails to get the team prepared.
