I may be mistaken but I'm pretty sure the reigns of Tyson had already been handed off to Kevin Rooney because Tyson resisted discipline and Cus saw Tyson as the golden ticket. Then Tyson started talking bad about Teddy (who was training other younger fighters still) and then grabbed his niece's ass or something and Teddy went crazy and took a gun to him. Teddy's book is an awesome awesome read. He's just as crazy as he seems but he's been there and done that with pretty much everything.
