Mike LaFleur and Matt LaFleur are now the first brother head coaches in NFL history to face off against each other. They meet Friday night at Lambeau Field when Mike's Chicago Bears visit Matt's Green Bay Packers. Neither brother expected this path when they were growing up. Their parents were both teachers, and football became the language they spoke together. Now one runs the Packers offense while the other runs the Bears offense. The reunion carries weight beyond the novelty factor. These aren't young coordinators trading jobs around the league. They've both climbed to the top of the profession, and they're meeting as division rivals in prime time. For a family that built itself on education and discipline, watching two sons become head coaches in the same division represents something neither could have predicted. The brothers have already talked about what Friday means. It's personal. It's historic. It's also just another game where one team wins and one team loses. That's football.
