The New York Jets no longer are the same team that came within a half of reaching the Super Bowl.
A transition to 2010 already has begun. The club on Monday parted ways with four assistant coaches and a consultant.
The changes won't impact the infrastructure of Rex Ryan's staff and mostly eliminates overkill. All of the aides answered to a primary position coach.
Gone are special teams coach Kevin O'Dea, assistant secondary coach Doug Plank, assistant quarterbacks coach John DeFilippo and defensive quality control assistant Brian Smith.
Plank, the most recognizable name and the inspiration for Buddy Ryan's 46 defense, was fired. The other three assistants didn't have their expired contracts renewed.
Plank helped secondary coach Dennis Thurman. DeFilippo, who coached the Oakland Raiders' quarterbacks for two seasons before joining the Jets, was an underling to quarterbacks coach Matt Cavanaugh. Jets offensive coordinator Brian Schottenheimer also is an accomplished QB guru.
O'Dea became redundant last year, when venerable special-teams coordinator Mike Westhoff returned from a brief retirement driven by medical issues. The Jets also have special-teams assistant Ben Kotwica.
Quality control coaches are tantamount to entry-level assistants. Smith had been with the Jets three seasons in that capacity.
Also leaving is pass-rushing consultant Chuck Smith, whom outside linebacker Clavin Pace credited with his big season. The former Atlanta Falcons defensive end helped out in training camp and was asked to stick around. He's leaving to become the University of Tennessee's defensive line coach.
