Kessler is getting old, GGG is getting into his prime. I haven't seen enough of GGG especially against top opposition but I think that his body work will get to Kessler late into the fight and he will TKO him.
GGG takes it, Kessler's best days are behind him and it would probably take a lot out of him these days to get down to 168
Kessler weighed 169 lbs for his fight against Green.. I don't think that making weigt is the problem for Kessler..
Hmm... interesting fight. Kessler more experienced. GGG the more youthful fighter. Both good. The issue will be where Kessler is with eyes and ambitions? A top prime Kessler beats any version of GGG, despite GGG being a VERY good fighter.
id be interesting to see how they match up side by side physically , the Viking warrior is always game , he mighthave left his prime but his power is still there , ggg is moving up a weight class so to me id be interesting to see who the harder puncher in this fight would be ......
