Based on my over 40 years boxing experience dummy. Based on the fact I have 2 eyes in my head and a brain behind them.
While G-man had awesome power he was very raw and crude. Huge gaps in his tool box mean he was not in GGGS league at all. GGG is the complete article - an all round superb boxing machine. He schools G-man all day, every day. Plus as previously mentioned G-man mainly feasted on smaller, punier light-punching opponents - basically cannon fodder.
Golovkin is more skilled than McClellan was if you deny that YDKSAB. McClellan has a chance to win because of his size/power advantage but not because of his skills. 2 bums outboxed him ffs
With each passing round an opponent survives, McClellans chances of winning shrink - until eventually they shrink to the size of, say, Nay_Sayers IQ (too small to measure!). :happy GGG has never been dropped - or even hurt that I know of. So G-mans only hope- that he could overwhelm GGG early, is remote indeed. About as remote as the chances of that imbecile Nay_Sayer ever learning about boxing. :deal
Was it his right hand or left ? Because ggg hasnt come close to being even semi hurt throughout his entire career. He knows his chin is granite and like mayorga he gives every single opponent free clean undefended shots in either round 2 or round 3. Most on here don't know the difference between being hit clearly and cleanly with good shots and a fighter being hurt. Ggg took several full on clean left hook bombs from lemme and walked right through him. The harder one hits ggg the worse it will be for you. He'll destroy your body before he kytfo with a head shot. IF full clean left hooks from lemme couldn't even stun ggg he has the first true unbreakable chin for an ATG... he's got every single attribute in spades to be the best ever h2h destroyer.. I can't, for the life of me, see him coming close to actually ever losing a fight
McClellan has beaten better fighters than has Bumlovkin. If you deny that then YDKSAB. Wake me when the Triple Duck comes off of his Bum of the Month Tour...
