A healthy Vitali is easily 10 times better a boxer than wlad at any point in his career. If Vitali wasn't injury prone, a pus during the byrd fight, and cut against lewis we could very well be standing here calling him the most unstoppable heavyweight that has every been but thats not the case in reality. Point is Vitali and Wlad are like Peyton and Eli. Vitali is older tougher and more proven vs better competition while Wlad can have his moments and then fold when things get tough.
