He doesn't have the legs. The guy that had good movement was in the other corner. He could fight going clockwise or counterclockwise or even effectively backing up. Then later in the bout he'd change up and go forward. Bowe does not have fast enough feet for this type opponent. And Riddick is a go forward type guy exclusively.
Yeah let's be honest here, guys - Bowe was simply robbed in the olympics. He was the real winner. Lewis should've offered to swap medals on the podium.
