If Spence were 6'4', built like a tank, with a killer jab and right cross and with footwork like Ali, he'd totally smash Hagler. Some of you may disagree, but it's true.
Hagler KO's him inside 3 rounds. But if Spence is allowed to stack his wraps he KO's Hagler inside 30 seconds because apparently applying tape before gauze gives you a vibranium fist that can punch through anything.
