What would have happened if a young Joe Calzaghe met Kovalev early on in his career?

[From Russia]

I just cant see a fighter without power defeating Kovalev. Sorry.

Remember jeff lacy. Joe takes Kovalev's soul over 12

Same thing that would have happened to any version of Calzaghe; he would have been beat down and stopped by the much bigger/stronger man.

honestly young calzaghe probably gets dropped and loses a decision..

if its 1997 joe vs 2015 kovolev,,, kovolev would beat him..
