Calzaghe DID sign an agreement for a rematch if he were to lose...and vice versa...but than again...after the fight...its HIGHLY unlikely that RJJ would want the rematch but if RJJ had won...then i think they both would've been up for it...considering that it would GREATLY scar his resume and EVERYONE would give him **** for it...including myself RJJ wouldve went into the bout a bit more confident considering he just KO'd him in the first time and Calzaghe would come much stronger because of the fact that he would've felt like he could beat him and just got lucky with that one shot... but lets face it...it didnt happen...and thats that...no use playing the "what if" game
