Fighters who didn't try enough against Wlad

[GAME]

Pretty much every challenger to wvlad accepted defeat and gave up mentally. All except Povetkin. I dont think that accusation could be levelled at him. He kept trying and fought out of his skin but wvlad was pretty dirty that night. Heavyweight vs super heavyweight but it was a good learning experience for the Russian who hadn't dealt with that style before
Hayes performance was very disappointing given all his talk before the fight
