GGG is almost 34 years old. If he gets rocked in this fight it will probably be all downhill from that point on. Sucks he's not 27. At this stage of his life he cannot afford any wars. Would suck if he ends his career for a win over David freaking Lemieux.
If you are 33 years old yea that's pretty much what happens. Prime is no more for guys at that age going through tough fights.
Holyfield went through 15 years of wars and at 48 beat SNV in a title fight :think remember, GGG hasn't taken anything close to a beating in almost 400 pro and ams fights
Don't believe it will be downhill from there on. Even if the fight becomes a war. Those do take their toll though. It may be an easy night for GGG or it might be a really tough one. Am thinking it could be a real war with almost anything happening. don't think it will be a cake walk for either fighter.
He will take care of Lemieux, trust me on that. He has another 3 years at the top too. Its then up to him whether as he starts to fade, that he retires with a great reputation... or fights on faded and starts losing.
Comparing GGG to Lemieux is like comparing Rocky to Mr. "T". Lemieux being Mr. T. GGG will not be able to keep Lemieux off him. Gets crushed in 3 .
