The biggest difference is on offense, where Chad Pennington has been simply superb since taking over for Vinny Testaverde at quarterback.
Pennington is completing over 70 percent of his passes, using running backs Curtis Martin and Richie Anderson as two of his favorite targets.
Wide receiver Laveranues Coles also has been a frequent target, and he leads the team with 38 catches. Tight end Anthony Becht, like Pennington a former first-round pick, finally has emerged in the passing game as he leads the team with four TD catches.
The Jets running game hasn't been nearly as good this season as in years past, with Curtis Martin on a pace to finish with a career-low 778 yards.
Martin does have a good backup in LaMont Jordan, who rushed for over 100 yards in last Sunday's 44-13 victory at San Diego.
Defensively, the Jets have a lot of big-name players but they give up an awful lot of yards. Turnovers did help them hold Minnesota and San Diego to seven and 13 points in the last three weeks.
The run defense is particularly weak, with opponents averaging a monstrous 5.1 yards per carry.
In the pass defense, cornerback Donnie Abraham has come up with an interception in three of the Jets' last four games.
The Jets special teams have been a strength all season, with standouts in kickoff returner Chad Morton and punt returner Santana Moss, who has touchdowns in each of the last two weeks.
The Jets' coverage teams also are excellent, although neither kicker John Hall nor former Dolphins punter Matt Turk is having a particularly good year.
