A weekly look at what the New York Jets must fix:

The Jets are into the "Missiles of October" portion of their schedule, as they face Philip Rivers, Peyton Manning and Tom Brady in an 11-day span. Unfortunately for the Jets, they're hitting this stretch with a defense that doesn't scare quarterbacks.

Oh sure, the Jets' defensive front will gets its share of sacks, but when it comes to making game-changing plays -- forcing turnovers -- its useless. Rex Ryan's defense has produced zero interceptions in four games. The only other team with an oh-fer is the New Orleans Saints, whose defense is headed by Ryan's twin brother, Rob. Talk about keeping it all in the family.

It's pretty amazing when you think about it: Opposing quarterbacks have dropped back to pass a total of 150 times against the Jets, and not one of those throws has ended up in the wrong hands. On Sunday, they travel to the San Diego Chargers and will face the hottest quarterback in the league. Rivers has a league-best 114.5 passer rating and has completed 70 percent of his attempts.

How does Ryan fix the takeaway issue? It's tough because they're undermanned at cornerback. The anticipated return of former first-round pick Dee Milliner should help -- maybe. Ryan is a man-to-man coach, but maybe he can change it up by playing more zone. Maybe he can play more two-high-safety looks instead of the usual one. He has to do something, because the Jets' bad start could turn ugly over the next 11 days.
