Maybe you all just have to realize that this team isn't very good. What you are really saying with all of this is that our coaching staff sucks which may be true. This is the year that will answer that question. In the meantime the 3-4 is a disaster for the Jets and most teams in the NFL which is why so few run it. Mangini has to eat some crow and at least go back to a defense that we were better in for years then the mess we have now.
One thing I respect is that they have Balls and NOT the ol Herm style of coaching and they have no issue releasing Kimo von suckoften and Anthony Smeagol.... So I can't understand why they are hell bent on the 3-4! Also, re-watch the games last year, It seems that the defense "Turned it on" for the rest of the season right after J-Mils Return in the Cleveland game. The Coaching philosophy changed and got more aggressive. I don't know if Bob Sutton is to blame or if he's just a pawn for Mangini but IMO Donnie Henderson should have stood. Sutton needs to go back to what worked in the 2nd half of the season. I even remember we went 5-2 on some fronts!
The Defense needs to STOP being so passive. Get mad and mean. Even though I hate to quote Herm "I quit on Chad and the rest of the NYJ" Edwards, the D needs to impose their will on the other team. The offense needs to START to get TJ and Leon in the same backfield and run some mis-directions. A fake to TJ and a toss sweep to Leon on a down like 2 and 5 would, let him get to the outside to use his elusiveness on LB's.
