His kids are grown which is why I mentioned two of them either got married or are getting married this upcoming summer. I only mentioned them because maybe he thinks life has passed him by with his devotion to coaching. He's got a younger girlfriend, time to enjoy life outside of football or at least coaching football. It's a long shot, but one day he will walk away from coaching.He's definitely unpredictable. No one will know his intentions until he decides to share them, and sharing info isn't his usual MO.
Both of his sons are coaches on the Patriots staff and his daughter is a coach at Holy Cross College in Massachusetts. So more "family" time wouldn't seem to be a factor in any retirement plans.
