No disrespect to Kelly Pavlik here, but he won his world titles from a disinterested Jermaine Taylor, lost them to an ancient scuffler and made a total of about 3 defences.

He was a tall middleweight, good chin and decent power.

In no way does that record compare to a guy who went 345-5 (or 8) as an amateur, won an Olympic silver medal, and annihilated a generation of middleweights while making 19 defences.

Golovkin would walk through Kelly, and because he wouldn't have to go looking for him, he would pulverise him within 6.
