I would probably go with Pavlick on this one as he doesn't seem to blow out later as a fight progresses. BHOP was all wriong style wise for him and as a result he looked terrible . Him and Froch would be more of a slugfest and I would have Pavlick edging it. I would expect a couple of knock downs on the way too.
Froch showed what he was made of coming back the way he did and has gained more repect from some , myself included.

Someone mentioned the physical size of Froch and yes he does look much bigger, Pavlick doesn't look much but musculature doesn't always amount to being stronger, as for JT calf muscles it's well known that black athletes do not generally have good calves, look at Tysons and his small ankles !!
