For a guy who might otherwise be the most boring individual in all of professional sports, it sure is fascinating to listen to a mic’d-up Bill Belichick.

The New England Patriots head coach turned 67 on Tuesday, and NFL Films celebrated by sharing a lengthy mic’d-up video of Belichick from his team’s Week 9 victory over the Green Bay Packers. From conversing with his coaches to lecturing his players to chastising referees, Belichick offered some surprisingly entertaining sound bites.

In other Patriots news, Tuesday marks the 20th anniversary of the day the franchise drafted Tom Brady. A rather significant day in NFL history, if you ask us.
