The New York Jets are atop the AFC East and tied for the NFL's best record.
Yet there are several areas they need to address during their bye week.
ESPNNewYork.com's Rich Cimini breaks down five areas the Jets must work on. Before the season began, it probably would have surprised most Jets fans to discover defensive issues are more common than offensive ones.
Here is Cimini's checklist:
Pass offense -- Mark Sanchez's accuracy must improve. He's completing 55.4 percent of his throws.
Pass defense -- Darrelle Revis' injury has been a serious problem. The Jets ranked first in pass defense last year, 22nd at their break.
Third-down defense -- The Jets rank 25th in third-down efficiency, allowing opponents to move the chains 42 percent of the time.
Red zone offense -- The Jets are tied for 19th, scoring touchdowns on 47.4 percent of their trips inside the 20-yard line.
Two-minute defense -- Cimini points out the Jets have surrendered points inside the two-minute warning at halftime or the fourth quarter in five of their six games so far.
