I disagree about mundine not having power, he hasn't shown it in awhile but he does have power in that right hand
The 2009 version of Roy Jones was an imitation of the fighter that dominated the 1990's. His loss to Green (his 5th in 10 bouts) was followed by another two defeats leaving his record at 6 from 13 after Ruiz at heavyweight. Of these 7 losses, 4 were by brutal KO.... Simple fact was that RJJ had lost his most valuable asset, his reflexes, leaving him vulnerable to any decent opponent possessing power. As for Shane Mosley he is also a different version of the 1990's champ but even today it requires a champion to defeat him. More importantly no one has been able to KO the great SSM and Mundine wont change that stat. If Mosley can partially replicate his effort v Margarito then he will assassinate Mundine.
Decent power, but not elite. It's on the positive side of average, but not by any more of a distance than his chin is on the negative side.
Being remembered for fighting a well known fighter,rather then being remembered for your other accomplishments e.g world titles,other big fights etc is the point I was trying to make.
