I see the Dolphins as a legit superbowl contender next season agree?

I am a huge dolfan and i was looking at their schedule today and i see them going 11-5 and winning their division. I see the Patriots on the downfall they are starting to get old and Brady has had injury problems. The Jets will be the main threat for the dolphins i think. I see Henne thriving for being the starter for a full season and Pennington guide him on the sidelines, the acquisitions of Dansby and Marshall will pay off greatly as well. Does anyone agree? How do you think they will do?
