I believe.....

[Primo Carnera]

Prime JC would beat prime RJJ

Prime JC was a SMW, Prime RJJ was a MW . Prime RJJ was 15 years before they actually met. Even as a MW , Prime RJJ beats any MW or SMW that there has been.
However , Prime JC (maybe even now with 6 months to get in shape) beats Prime Carl Froch

When do you think Calzaghes prime was?
probably between beating Jeff Lacy in 06 and beating Kessler in 07, at least they were his defining fights. 1 year after that he beat RJJ. Why? When do you think his prime was?

You think Jones prime was 93?

[COLOR="red"] yeah, I do. From 93-96 before he got DQ'd against Montell Griffin, he was invincible. After that, by his own admission, he felt robbed of his career target Of being undefeated, so had to do something else that would be pretty unique, and that was to go up all the weights culminating in being HW World champ. I don't think that he was ever as invincible again. Again, when do you think his prime was?
And I BELIEVE Prime Hatton beats Prime Khan.COLOR]

Don't know what you've done with the quotes there.

Calzaghes real prime was early 2000's. He had the stamina to fight the way he did later in his career but he also actually punched with authority before his hand problems. Ask Eubank how hard he could hit. He was very good and adapted to not only stay competitive but dominant this is why Hopkins priced himself out of a match he had agreed to back in 2003.

Yeah, I'm not the most gifted when it comes to techy stuff, fucked up those colours and quotes.
I hear what you're saying about JC before his hand problems, but I actually think that BECAUSE of his hand problems, it made him a more rounded , better boxer. He got better as a boxer as his career went on.
