Making the playoffs is secondary for me right now.
I want the Jets to play well, win the game, and end the regular season on a high note. That worked for the Falcons 2 yrs ago. They had blown their chance at the playoffs with an up and down season and were hell bent to win the last game to finish 9-7. They went 14-2 the next year. The same with the Steelers in 2009.
Beating Miami is also good to show that the Jets haven't quit on Rex.
