Should Calzaghe retire?

[pelonxsoldier28]

he Shouldn't Retire Untill He Gets A Win By Ko.

I Second That. Joe Likes To Really Fight, Put A Guy Like Pavlik In His Facei Wanna See And There Will Be No Covering, Just Brawling. Thats The Fight

Retire...there's nothing left for him

Yes he should retire. He's undefeated with over 40 wins, and he obvously isn't starving for money (agreed to fight RJJ for 50/50, he cares more about pride), there's no need for him to fight anymore. Beating the guy he's been wanting to fight for over a decade is the perfect way to finish your career.

Dawson, please. Beating Dawson proves nothing.

What does beating a 40 year old RJJ who hasn't beaten a good fighter in five years prove?
Dawson is the best in the division and Calzaghe-Dawson would be in my mind for the undisputed light heavyweight title.
