I like Roy Jones Jr. to clearly outpoint Marvin Johnson...Marvin might catch him and hurt him a few times...but for the most part, a prime Roy is two steps ahead for the entire fight...Jones can get the angle on Johnson all night moving to his left...I really like Marvin Johnson, but he is a one armed bandit...(his left) Jones Jr. by UD
Roy Jone is quite possibly the greatest fighter of all time regardless of weight. I see Johnson walking into numerous right hands from Roy who toys with him at will, like cat and mouse. No light heavy has what it takes to compete with prime Roy who is like the Ali of lightheavyweights, only better.
I think the longer the fight goes, the more it plays into Marvin's hands, up to 8 rounds, it's Roy's fight, after that Marvin has the stronger chance to win.
Another bridge too far for the gallant Marvin...Jones stops him in 8 or 9...maybe coming close to mastering him like Eddie Mustafa did.
