I would also add that for this particular team (who has a giant vacuum at tight end and a running game comprised entirely of hopes and dreams), red zone attempts are particularly worthless. If you have a great running game or short passing game, it's easy to convert red zone attempts into TDs. MIA needs to be scoring TDs over the top.
This is my fear for this years' team. It was great that they picked up the much needed WR's, but they blew off Bush with no replacement. They got rid of Fasano and replaced him with Keller who is now gone for forever. I know many on this board aren't fans of Bush and Fasano, but they scored all the TD's last year. If the fins kept those two players, along with WR and defensive improvements I think they could have been a contender. Now, unless a couple guys really step up their game, and they catch some breaks, it's going to be another mediocre season.
