He did have two hellish duels with the great heavyweight ezzard charles pretty well. And I think he would take Lamotta to town, as for more recent fighters. I think he'll have a far easier time vs 'Tito' than he would against Oscar. I actually favour Oscar over Burley.

As for legit middleweights. I would favour Hopkins over him but not Hagler. That's simply because I think hopkins would give him angles and could fight on his back heel better than Hagler, as well as the fact I think hopkins would be the natrually bigger man.
