Mangini's unwillingness to switch to 4-3 hampering 'D'
Updated as of 11:30 p.m. Sunday Sept. 30
When Eric Mangini was brought on board as head coach of the Jets, he instituted the 3-4 defense, which was so successful during his tenure as Patriots defensive coordinator. The problem is that the Jets’ personnel is far more conducive to running a 4-3 defense. According to daily Jets observers, Mangini’s stubbornness in not allowing more 4-3 looks is hampering a unit that has struggled to date. ILBs Eric Barton and Jonathan Vilma and NT Dewayne Robertson have actually looked better in recent weeks, but nonetheless they’ve collectively struggled in the system. So have OLB Bryan Thomas — who was drafted in the first round in 2002 to play end — and DE Shaun Ellis, although Ellis had a sack in last week’s loss to the Bills. Many NFL teams that are labeled as having 3-4 defenses actually operate with three D-linemen only about 50 percent of the time, whereas the Jets have an additional body on the line only about 10-20 percent of the defensive snaps. The feeling is that until Mangini trades some speed for size, his defense will continue to underachieve — especially against the run.
