The rivaleries are gone with Oakland and KC so that hurts. It feels odd playing the Rams and 49ers twice a season and it also makes you feel like an expansion team.
Last season was difficult because there is still no reason to really "get up" for any opponents in the division since there isn't any hate like what had been developed over 20+ years in one division. Hopefully in a couple years we will feel that way.
On the plus side we get to see a lot more teams we aren't used to seeing like Washington, the Giants, Green Bay, etc.
