LaMotta would have been laughing at Graziano's attemps to ko him, and would have worn him down to a frazzle for a tko in the 10th or 11th.
I gotta go with LaMotta from what I've read Graziano never wanted to fight Jake he used to call LaMotta the police man (or someting along those lines) cause LaMotta used to fight everyone that Rocky didn't want. I also heard that the fight was almost made but Rocky punched a tree breaking his hand because he didn't want the fight although I doubt this is true.
