****! i'm visiting a friend and in a rush but i'm inclined to think jack's huge size and strength advantage could make this a tough assignment. over 15 i'll take canzoneri in a close decision, based on movement and provided he can avoid getting cornered by the bigger man. jack didn't have a huge punch and would rely on pressure and physicality to win and i don't see he being able to exert the consistent pressure needed to win
Canzoneri's style works quite a bit for Jack. He likes to stand in range of his opponent with his hands down and countering them. If he does this Jack's size advantage, punch and pressure may win him the fight. But I guess Tony would fight an more intelligent fight and eek out a decision.
