Geez, for someone who is a self-professed Dolphins fan you sure bring up the Jets a whole lot. Admit it, you're obsessed just like the preteen girls are with Bieber. It's okay. I'm sure you can buy a 2008 Favre jersey somewhere on the interwebs.
As for Miami having a QB...that is rather debateable.
These are the statistics for two NFL QBs during the 2012 season. The first is Ryan Tennehill. The second is a mystery QB.

Tannehill isn't significantly better than Mystery QB, and has the benefit of playing one extra game than the Mystery QB last season. Additionally, Tannehill plays for the Dolphins who no one respects. The Dolphins last good season came with a blind head coach. Also, if they played all their games in S. Florida, they would have a shot at the playoffs, but come November/December the Dolphins will choke as they always do. No worries, they'll won't suck enough and will miss out the Teddy Bridgewater and J. Clowney sweepstakes.
