Vikings Head Coach Mike Zimmer has a history in the NFL.
He was the Defensive Coordinator of the Dallas Cowboys for seven years, four of them being under the legendary Bill Parcells.
In 2007, he was the Defensive Coordinator of the Atlanta Falcons, and held that same position with the Cincinnati Bengals from 2008-13.
Zimmer has crossed paths with several active head coaches in league today. Steve Serby of the New York Post writes that Zimmer is cut from a legendary coaching cloth, that has proved Super Bowl success for three other coaches in the NFL.
