Now that his shaky whiskers have been exposed, I doubt it. Once they crack, they usually don't come back.
Well of course there is hope, but only if PWilly puts his mind to it. I didn't like what I heard, tho, after the brutal ko by Sergio. He said he was fine and cool about it, like it was no big deal, but said that the fighting style he uses he's always going to use it and he was comfortable with it. In another words, he's stubborn and not going to do much about his defense. I think Steward who has a history with working with tall lanky fighters would be great for Williams. He needs to fight more at a distance behind a southpaw jab and more waist movement. He needs to clinch and push down on his opponents like other Steward alumni's Lewis and Wlad did. Williams still doesn't take full adv of his size. Urgently needs to.
Definitely got to get rid of that trainer. When I was criticising him a while back, people got on me and got upset, but I recognize a bad trainer when I see one.
