Unfortunately, the Jacksonville game pretty much ended the Dolphins' hopes. A win there, and Miami would be sitting very well at 7-6, in a tie for the final play-off spot with Jacksonville, the Jets, the Chiefs, and the Broncos. The Dolphins would have essentially controlled their own destiny, having the tiebreaker over Jacksonville and KC, and a win over the Jets would give Miami a better record. The only outside help that would have been needed was one more Denver loss.
As it stands now, Miami needs to win out AND needs a ton of help.
Sigh.....oh well.
