jeah if wlad had vitali's chin then none of todays heavies would be able to beat him, because even with his not so great chin there really are maybe one or two around that can. He would have never gotten starched by sanders but instead pounded him into submission probably even quicker than vitali did, as for brewster the whole fight would have been like the first 4 rounds of their fight, purity might have still gotten a win over him since that in my eyes was really a stamina issue, it was in the 11th round or something and the corner threw in the towel he wasn't knocked down or anything. Wlad might not have the chin but certainly has the determination and heart of a champion, and there's been a few greats with not so great chins, so if he unifies and defends the title against top competition he still might enter that select group. If he had his brother's chin we might already be talking about him as an all time great, as is though he's just the best of an average bunch for right now.
