Moore played football under the legendary Coach "Bear" Bryant.
And served in several roles over the decades at the university before becoming athletic director in 1999.
He is most praised for hiring current Coach Nick Saban.
Alabama fans are sad to hear the news Moore is stepping down.
"Just hurts to lose such a historic figure in Alabama history, who is a player, a coach, and athletic director. He's the only person I know that can wear ten rings, one on each finger for all the national championships he's been involved with. Such an iconic figure.It hurts any institution to lose. Just going to be a heartfelt loss for the University of Alabama," said one fan.
73-year-old Moore has been hospitalized recently with some heart complications.
"Coach Moore has had some respiratory issues in the past. I noticed last fall Coach Moore looked a little slower and just didn't seem to have that pep in his step that he's had in years past. You could kind of sense something just wasn't quite right," said Sports analyst John Longshore.
Fans say they felt a personal connection with Moore.
"I hate it for his health. I hate to see him go. He's an Alabama man," said Lynn McDaniel.
"Personally, I've always admired Coach Moore. I remember the first time I met him. I was fifteen years old and he's remembered me ever since," said Longshore.
And they are sad to see the end of an era.
"It's sad because he's been there so long. He's been there about as long as I've been liking Alabama. He's got 10 national championship rings. Going to be a different era. But he's doing the right thing," said Bo Burt.
Moore will now serve as assistant to the president at the university. No word yet on his replacement as athletic director.
He is a legend in the Alabama football program with 10 national championships. But University of Alabama athletic director Mal Moore is stepping down.
For many fans, Alabama football and Mal Moore go hand in hand.
