The college football world lost one of the game's legendary coaches Monday night, as Mississippi State head coach Mike Leach died of complications from a heart condition. He was 61. 

Leach spent 21 years as a head coach, with stops at Texas Tech and Washington State before becoming the head coach in Starkville in 2020.

Kiffin, who also coached against Leach when both were in charge of programs in the Pac-12, released a statement Tuesday remembering "The Pirate."

"I truly loved Coach Leach and every minute I shared with him," Kiffin said in a statement. "I have been able to work with several of his former players and coaches, and they have told me so many stories about the impact he had on their lives. Going back to our years together in the Pac-12, I have always felt tremendous respect and admiration for coach, his unique personality and his innovative mind, and I can’t imagine college football without him. I’m grateful to be part of his final win, hug him and watch him walk off like the winner he is. 

"I know God is welcoming home the Pirate now."

"There is no way I would be where I am today if not for Mike Leach and everything he taught me about the game," Kingsbury said, according to ESPN. "Truly one of the most innovative offensive minds in football, he was more than a coach. He was a mentor, a friend and one of the most special people I've ever met."
