Toughest decisions cornermen have made?

Fritz Sdunek did one helluva job by stopping the Klitschko/Byrd fight.
Klitschko was taking hellacious Hayemaker after Hayemaker against a blown up Middleweight with an injured shoulder.
The only reason why Vitali can speak without slurring his words is Sdunek. Byrd was on a mission that night.
