The Dallas Cowboys introduced their new defensive coordinator on Wednesday. Or perhaps re-introduced is more accurate. Mike Zimmer’s first defensive coordinator job was with the Cowboys, and he was on the staff even longer. He first joined the team in 1994 as an assistant, meaning that he was there for the last Super Bowl win for Dallas. Including his time after being promoted to the DC job in 2000, he has a total of thirteen years in that capacity, including stops with the Atlanta Falcons and Cincinnati Bengals, and then spent eight years as head coach of the Minnesota Vikings.
