The Jets parted ways with four assistant coaches and a consultant on Monday. Assistant defensive backs coach Doug Plank, assistant quarterbacks coach John DeFilippo, special-teams coach Kevin O'Dea and defensive quality control coach Brian Smith won't return. Plank was fired, while the other three won't have their expiring contracts renewed. Pass-rushing consultant Chuck Smith left to become defensive line coach at the University of Tennessee. "We're going to have, unfortunately the way everything is, there's some guys on our staff that their contracts won't be extended," Ryan said. "They ran out, and some contracts will not be extended, and that's unfortunate because some guys did a great job. I'd really rather not get into the particulars of things right now."
