My Roy/Joe prediction.

[Taeth]

Joe in round 6. As Joe has stated he's gonna pick and sit down on his punches rather than throw flurries.

Jones legs look really shaky in the openning 2 rounds and if Joe hasn't taken him out by then, then it will be around the 6th.

Jones just doesn't have the movement to keep out of harms way for long enough and his chin is not there anymore.

Could be reminiscant of Lennox vs Tyson.

I doubt Tyson was never(even if he reached his potential) anywhere near as good as Roy is. And Calzaghe doens't not only have the power Lennox had, but he isn't as good as Lennox was.
