Details were still being worked out on Friday, according to the person, who spoke on the condition of anonymity because the team hasn't announced the decision. Mayo played eight NFL seasons and won a Super Bowl ring with the Patriots during the 2014 season.
Mayo’s hire comes a day after Belichick agreed to part ways with the Patriots after a 24-year run that included six Super Bowl wins.
Mayo immediately rose to the top of the list as viable Belichick successors since the Patriots took the unique step of announcing they were giving the assistant a long-term extension last offseason. Mayo, along with Belichick’s son and fellow linebackers coach Steve Belichick, handled the play calling duties for the Patriots defense over the past two seasons.
Though it’s unclear what the terms of Mayo’s deal prior to last season entailed, it came after the 37-year-old interviewed for multiple head coaching jobs in Philadelphia and Carolina each of the past two years.
