If Pac beat Oscar that would be pretty amazing considering the size differerence, and the fact that Oscar is actually still a good boxer. Jones is shot, so its an easy question for me to answer.
OOPS: Wrong way round. If Oscar beats Pac thats probably worse than Calzaghe beating Jones, Oscar may still be the best at 154 and beating up a guy 3 weight classes below you is a little harsh.
I dont think either means anything, Oscars huge compared to Manny, Manny is muscle bound but you cant increase the size of your skeletan and he still has that featherweight type built, Oscars forearms and shoulders, his back are real developed, plus lets not forget Oscars still a top fighter, he has a great jab, can still box well on his toes, Manny is just too small, he'd get outboxed and hit with heavy punches, that left hook would do damage too, its just not a good fight....Jones is obviously a past his prime fighter but he still has flashes, he still has such natural ability, so it means a little more, but we still know its a fight that shoulda happened in like 2002
i dont care to see either, but i'll go with Calzaghe over Jones.
at least Pac has a chane Jones cant take it on the chin these days and his stamina wil only allow him to fight for 5 rounds
