Legendary six-time Super Bowl champion head coach Bill Belichick once again has his New England Patriots in playoff positioning as the future Hall of Famer continues to prove his worth as an all-time great.

Now in his 23rd season as the Patriots’ head coach, Belichick also finds himself as the second-oldest man at his position in the NFL at 70 years old. It’s in this that some have bandied about the possibility that Belichick could end up retiring at some point soon.

NFL insider Josina Anderson from CBS Sports touched on this recently, indicating that there’s been talk about one of the three longest-tenured head coaches in the NFL stepping down after this season as teams prepare for potential vacancies around the league.

“There’s talk behind-the-scenes as to whether any one of 3 of the NFL’s longest tenured head coaches will step down after this season or next as these lists get compiled in preparation for vacancies,” report on head coaches who might step down in January.

With New England since all the way back in 2000, Belichick is the longest-tenured head coach in the NFL. He’s followed in line by Pittsburgh Steelers’ Mike Tomlin and John Harbaugh of the Baltimore Ravens.
