Joes speed factor would come into play but remember that other fast guy Lamotta beat SRR........... So you never know
I don't care about nationality. This is a styles thing, Calzaghe is all wrong for LaMotta, it's that simple. And I don't have what ('enmity'?) for Ali and Walcott?
The only time I look at birthplace or hometown of a fighter is to see if I have access to primary sources (local newspapers) for him if I'm going to learn something about him.
I definitely go for Joe here. LaMotta only has strength on his side but Joe would use his strength against him. Calzaghe UD, probably really wide.
