He held his own with some of the better Heavys...was losing to Vit before injury and get dominated by Vlad but did great vs Tua and had some nice wins over Holyfield,McCline and others, I thought Golota was a close win for AG but it was close and I thought Oquendo beat him...still avoided by many and a tough southpaw heavyweight with heart and a bag of tricks
Not great, but good. Not sure how he do against the all time elite, but he does have that style that may pose problems to fighters like Joe Louis. But in the end I would like to belive Louis would grind him down for the ko or tko win. Perhaps like the Farr fight. Would not shock me, if he does not off one or 2 atg heavyweights.
