Mississippi State head coach Mike Leach passed away on Monday night at the University of Mississippi Medical Center in Jackson, Mississippi, following complications from a heart condition. He was 61.

There’s been an outpouring of support and multiple tributes published since his passing as the college football world continues to come together to appreciate the life of a truly one-of-a-kind person and offensive mastermind.

Alabama head coach Nick Saban released a statement on Leach after the news broke.

“Mike Leach was a friend, and we are deeply saddened by his unexpected passing,” Saban wrote. “I thoroughly enjoyed getting to know Mike over the last several years. I never knew quite where our conversations were going, but they always made me smile. He was an offensive innovator who always did things his way and was admired for it. His teams were well-coached and extremely challenging to defend. They played with poise and toughness, which is a credit to his leadership. Our thoughts and prayers are with his wife Sharon, their children and the entire Mississippi State family.”
