Who will be our first loss to??

I know sooner or later we will eventually lose but I'm wondering who we will lose to. Its somewhat of a scary thought at the same time.[xx(]
I think we might lose to Seattle first. I know we will get a scare from playing the broncos but i could see us winning that one. Other then that we play a stretch of a lot of home game. It also will be a good thing because we play a lot of weak defensive team. Try naming the best defensive team this year??? Id like to know who that team is.[}:)]
