I think Mundine would trouble Joe for a couple of rounds with his speed and then Joe would be all over him possibly getting a late stoppage.
I would favour Calzaghe to win a decision but I think Mundine was good enough to pinch a few rounds. I actually think it would’ve been a good fight both guys had very fast hands.
Mundine at his peak ( which was short ) was no joke! Not many outside of Australia know how good he was.
