Nick Saban and his decision to retire from coaching reportedly came down to age and health concerns.

Saban, 72, made things official on Wednesday after 17 seasons with the Alabama football program. The impact that he had on the game of college football won’t be forgotten any time soon. The Crimson Tide head coach reportedly cited the reasons in order to explain the move to his football players.

To say that Saban loved what he did was an understatement. He reportedly treated Wednesday as a normal workday, attending the SEC head coaches call. Saban also interviewed candidates for some of the football staff openings at Alabama. One position came open recently after defensive coordinator Kevin Steele reportedly decided to retire from coaching on Monday.

The Crimson Tide were written off earlier in the season after losing to Texas. Alabama then battled back and won the rest of its regular season games to earn a spot in the SEC Championship. After beating Georgia and ending the unbeaten streak, Alabama made the College Football Playoff. The season ended after a heartbreaking overtime loss to Michigan in the Rose Bowl.

Hopefully, the Saban family is doing well after this kind of news. The college football world will definitely miss seeing Saban on the sidelines.
