Aikman paid tribute to his former coach on Monday.
"Lost a good one today🙏🏼 Ernie Zampese was one of the brightest offensive minds in the history of the game - many of his offensive concepts are still being used to this day. He was my offensive coordinator in Dallas from 1994-‘97. One of my most memorable moments was winning Super Bowl XXX in Tempe, AZ in 1995 and Ernie getting the Super Bowl ring that had alluded his HOF career. A friend and mentor to so many.
Prayers are with his wife Joyce, son Ken and his entire family.
Rest In Peace Ernie," he wrote.
Our thoughts are with Ernie's friends and family members.
May he rest in peace.
