Hagler actually performed better against larger men and fighter who came at him.

Of course we've been over this, but Hagler was way past his best in the Leonard fight. Also, Leonard presents an entirely different set of challenges than Calzaghe. Like I said before, Hagler was great against guys who would come at him. Also, Hagler lost the Leonard fight just as much as Leonard won it by starting out slow and playing around with him. He gave away the first three rounds completely and it cost him the fight. But I digress.

As far as Hagler's size, he's about the same size as Robin Reid. And Calzaghe came pretty close to that fight. Say what you want, but when he was champion, he DESTROYED guys on Reids level, people like Minter, Anterfuermo, Hamsho, and Fuli Obel.
