He's an addict. I love him, he's safer than he was before his first "retirement," and he's better off performing in WWE than the indies or AEW, but he's absolutely an addict. He'll do this as long as he's allowed to. Supposedly he's retiring after his next contract is done but I don't believe that shit for a minute.
He's my favorite current wrestler (and my pick for best in the wooooooooorld currently working) but yeah, dude is fucking insane.
Cindy, I know you weren't watching at this point, if you have access to the Network, watch his match with Bork Laser from Survivor Series 2018. He's so goddamn good.
