Considering Clottey's knock-out history - you'd probably lose your $$. Berto may not be the best defensively, but based off of his last performance, he would flurry and clinch. If Clottey came close to hurting him, he would just clinch. Each round, Clottey's chance of getting a ko would diminish, as he becomes less effective towards the end rounds. He had Corrales (RIP) very hurt and couldn't finish him, and Chico was already towards the end of his career and fighting at his highest weight ever. If the fight should happen, save your money. I do think Clottey would win, but by decision, not knock-out.
Clottey called out Berto after he spanked Judah. The Berto camped wanted nothing to do with Clottey. Berto would get smashed up.
Everyone says he'll get smashed but they refuse to say how. So how? Styles make fights and I think berto has the hand speed and footwork to give Clottey trouble. And Clottey can't ko him. He has very little KO power.
