At middle weight Joe would still be the taller and longer fighter ,so not so unequal terms. 15 rounds, who's walking out the winner?
Calzaghe wouldn't be able to make middleweight, unless you mean the 20 year old am. LaMotta would obviously piece such a man up.
Calzaghe isn't making 164 in the same day era. Calzaghe walked around at 190 and had to cut down to make 168. Having a whole 24 hours to rehydrate makes a big difference. Size and handspeed would be a problem for Jake. Plus, Jake couldn't hurt Calzaghe. Then again, Calzaghe probably could hurt Jake either. I'll take Calzaghe on points. If Calzaghe fought in Jake's era, he would be at 175 or maybe even heavyweight.
Exactly, two different animals, though Jake too was a MW cum L-HW, but JC is too big and should point his way to victory or better.
This is the correct answer. Either Calzaghe comes looking like a waxwork, half-dead to the fight and LaMotta massacres him, or Calzaghe somehow makes 160 safely (and I can't see how, but let's imagine it for the sake of argument) and then JLM is royally ****ed because Calzaghe was bigger, longer and much faster than him with a Formula 1 type boxing engine. He might even carry some power at 160 which would be the nail in the coffin.
it could only ever be a Catchweight fight at say 170lbs, which would still suit Jake who wouldn't have to shake more than a few pounds or anything at all, but JC still would win. JC's never making MW and Jake would lose to the Bigger man any way you slice it.
Calzaghe was typically 178-180lbs on fight night at SMW*. I think my Mrs. could beat him if he'd somehow made 160lbs on the day of the fight. * source = Joe himself, in his autobiography.
