Halftime: Chargers 21, Jets 10

A quick take on the first half:

1. Where is the Jets' defense? They dominated Luke McCown and Matt Moore of the Jaguars and Dolphins, respectively, but they get exposed against quality quarterbacks. Philip Rivers led the Chargers on 76- and 87-yard TD drives, with a strong running game and passes to his RBs and TEs. For the most part, the Jets took WRs Vincent Jackson and Malcolm Floyd out of the game, but they struggled with TE Antonio Gates (2-yard TD). What else is new? At time, the Jets appear clueless against tight ends -- see the blown coverage on Gates' TD catch.

2. The Jets' linebacking corps is a mess. This week, they tried Josh Mauga at OLB, replacing Jamaal Westerman, who replaced the injured Bryan Thomas. Mauga was blown up on the Chargers' second TD, a 1-yard run by Mike Tolbert. In the second quarter, ILB David Harris left the game with an ankle injury (questionable return). He was replaced by rookie free agent Nick Bellore. The lack of depth is glaring; poor job by the personnel department.

3. Two of the Jets' smartest, most fundamentally sound players -- C Nick Mangold and S Jim Leonhard -- committed big penalties. Mangold's holding call nullified a 23-yard TD pass to Santonio Holmes and Leonhard was flagged for pass interference on Gates -- who else? -- at the Jets' 1.

4. The Jets made two turnovers that led to 14 points. On the Jets' first possession, TE Dustin Keller fumbled -- actually, it was ripped out of his hands by LB Donald Butler, who returned it 37 yards for a TD. Later, QB Mark Sanchez made a horrible read (and throw), floating a pass to WR Plaxico Burress that was picked off by S Eric Weddle. The Jets were in scoring position, and that cost them at least three points. The Chargers took the bal and went on a long TD drive.

5. The Jets simply don't look like a playoff team. Their offense finally is showing signs of life and -- what happens? -- the defense regresses. That's what happens to mediocre teams.
