Calz v Hearns at 168 And 175 ? I like Joe in either division but not without trepidation. Joe could be hit and hurt by the right hand, something Hearns will be happy to demonstrate.
Joe by stoppage at 168. But Tommy by decision or KO at 175, as I think he was actually better at LHW than Calzaghe. His body was more defined, still had some speed and he can still destroy his opponents like the iron chinned Dennis Andries. If Joe gets nailed with the right hand multiple times, then I see Tommy getting him outta there.
I make Joe favourite at both weights,although there would always be a risk of Tommy catching him with a right hand.
