If Williams can make it out of the early rounds he stops Shavers within 10. Shavers wouldn't have the stamina to keep attacking for very long.
Shavers is the bigger, more concussive puncher....and I can't get the thought out of my head that Shavers just gets there hard and first and often.... Shavers has "gotten up" more than Williams did and fought and did well against higher-caliber fighters, overall. I like Shavers.
