Whenever a defensive-minded head coach is hired, the immediate follow-up question is who his offensive coordinator will be. That's a question the New York Jets will have to answer after hiring Aaron Glenn as their next head coach.

Aaron Glenn is back with the Jets. From 1994 through 2001, he was a defensive back for the team, learning from some of the best coaches of all time.

When Dan Campbell, another former Saints assistant and the head coach of the Lions, took over in Detroit, he brought Glenn with him to lead the defensive unit. Now, three seasons later, Glenn is adopting a similar staff-building approach to Campbell's.
