Mike Holmgren said he would consider returning as a coach if one of the seven NFL teams with a vacancy contacts him, according to ESPN.
Holmgren, 64, left his executive position with the Cleveland Browns during the season when Jimmy Haslam took over as the new owner.
"If anyone is interested, I'll listen," he said, though he added that he is not aggressively looking for a job.
Holmgren, who won a Super Bowl as the Green Bay Packers coach and also took the Seattle Seahawks to the Super Bowl, is living in Arizona.
Holmgren did not say which teams he is interested in coaching or if he has been contacted.
