The carousel for NFL coordinators is far quicker than that of head coaches.

Darrell Bevell and Josh McDaniels, offensive coordinators for the Seattle Seahawks and New England Patriots, are two of the longest tenured in the NFL.

Bevell has been with the Seahawks for four seasons, making him the second-longest-tenured coordinator in the NFC behind Pete Carmichael of the New Orleans Saints.

McDaniels and Todd Haley have been with their teams for three seasons, making them the longest-tenured offensive coordinators in the AFC.

Every other NFL team has hired at least one new offensive coordinator within the past two offseasons.
