Buffett is the second-richest man in the world, according to Forbes, with an estimated net worth of $71.6 billion. A noted Nebraska Cornhuskers fan, Buffett and Suh have been friends for a few years after former Nebraska football coach and athletics director Tom Osborne introduced them.
Though Buffett declined to comment on whether or not he's given Suh advice about his pending free agency, he told The Detroit News he hopes Suh re-signs with the Lions.
"I hope it isn't his last. I hope he stays in Detroit," Buffett said. "It's his call, obviously. He's a hero in Detroit; he deserves to be one. It's a terrific city, it's on the way back and I just think it'd be great if he sticks around."
