"Jackson had very good power". That's like saying Larry Holmes had a "very good" jab. Jackson is one of the hardest punchers ever P4P.
Mike beats GGG. Thats all there is to it. As for Jullian Jackson, Well if he can land on GGG's chin, which is fairly easy by the way, he may very well knock him out.
No ****ing way does GGG hit harder than Julian Jackson...Daniel Geale got up after the GGG KO...he was lucid. Now remember back to THAT KO of Herol Graham and trust me when I say that Herol Graham was 10x the boxer that Geale is...Julian Jackson is one of the hardest P4P punchers in history, GGG is on a par with say...Nigel Benn who was absolutely devastating at 160 but no Julian Jackson.
