GGG if he carries his power well and if Froch chin is somewhat gone which i believe it has after Groves. Froch takes way to many shots without his chin he would never have got beyond european level. GGG will land heavy heavy leather if Froch takes it then carries GGG into later rounds he can win especially with the extra weight he would have on GGG and we still don't really no if GGG has the stamina because he blasts everyone out.
If Froch thought that Groves hit hard, well; He'd be in for the shock of his life against GGG! GGG within 3/4.
Depends on GGG. If he moves up, and retains 90% of what he appears to be at MW, then he wins and wins fairly easily. There is a big size difference between MW's and SMW's though. I dunno why this is but SMW tend to be a fair few inches taller, given there is only 8lbs of a difference.
Groves may well punch harder than GGG as good a puncher he is at middleweight Groves is one of the confirmed big hitters at 168
