RIP former Cowboys defensive coordinator Monte Kiffin.
One of the greatest defensive minds in NFL history has passed away on Thursday.
Monte Kiffin, who coached in the league for nearly 30 years, including a stint with the Cowboys, died at the age of 84.
The news was announced Thursday by Ole Miss, where his son Lane Kiffin is currently the head coach.
Kiffin spent the 2013 season as the defensive coordinator as part of Jason Garrett’s staff. The Cowboys finished 8-8 that year and missed the playoffs on the final week of the season.
