Rex Ryan's uphill battle
Great defense guarantees playoffs, but a Super Bowl needs more from Mark Sanchez
In all of the cacophony and turmoil surrounding the Darrelle Revis contract situation, there has been one consistently reassuring voice for Jets fans. Rex Ryan has stated repeatedly that the Jets' defense will "play great" and has even gone so far as to say that New York will have the best defense in the league.
If all the talk about the defense proves correct -- and the running game of Shonn Greene, LaDainian Tomlinson and others grounds out yards -- then, yes, the major limiting factor could again be QB Mark Sanchez; he really didn't perform well last season but was good enough to get New York to the AFC title game.
So how well will Sanchez have to play to get the Jets back to that level and beyond?
If history is any indicator, unless he somehow finds a way to crack the top 10 in passer rating, New York almost certainly won't make it to and/or win the Super Bowl no matter how great its defense plays.
