Over at Joe Roark's board they discussed Casey Viator's "finger amputation" and said he just lost the tip of a finger, not the whole finger and everything got exagerragted. I don't know either way, just putting that info out there.
Casey was detrained and off juice, the hopped back on steroids and muscle memory did the trick. It seems like people are forgetting how massive the guy was even at age 19. It's not like he gained fresh new mass during the "Colorado experiment." Then there's the tales of him doing extra volume training on his own, etc.
