Mike Tomlin was 29 years old when he first cracked into the NFL as a member of the Tampa Bay Buccaneers in 2001 as their defensive backs coach. He was tasked with coaching the likes of Hall of Famer John Lynch, who was older than him at the time. Jon Gruden was acquired to coach the team the following year, and the two coaches spent the next four seasons working and growing together.
On Sunday, they will be on opposite sidelines for the first time in their professional coaching careers, with Gruden having returned to the Oakland Raiders for the first time since 2001.
