Then they didn't have a chance to begin with. The good teams survive big injuries like this because they have good coaching and they have depth. Did the Patriots fall over and die when they lost Brady a few years ago? Even though they just missed the playoffs, they finished something like 11-5.
Coaching and depth ... Well, the Jets definitely don't have depth thanks to all the draft picks this team has lost due to Mr. T trading up the draft board like a drunken GM the past several years. Whether they have good coaching remains to be seen--I certainly have my doubts based on the way they have played the past two games.
