Ruiz face would be badly swollen if DR.Ironfist was there fighting him. Thats how much better Vitali is than Joshua.
Ruiz would be covered with blood from head to toe after fighting Vitali Klitschko. Arreola was way better than Ruiz
Vitaliy was a higher class of a fighter than Joshua. After KlitschKOs there is a little excitement at heavyweights.
