I don't think Vitali would avoid haye, but i honestly feel if haye grows the balls on fight night, he would beat this version of vitali. It'll be the right time to call it a night on his career now.
Haye struggled to get going against Wlad cos Wlad despite being chinny does control the range fairly well and is quick and decent on his feet for such a big man. Haye found him a more difficult target than he expected, and then accentuated this by not going for it as he should have done. I expected him to be cautious, but i think he thought sooner or later he'd land something major and then he'd go bombing looking for a finish. He never really found the target with the bombs he was after, so spent the fight circling and waiting for something that never came.
To be fair its not like Wlad ripped any trees up that night either. He never came close to halting Haye and i think of the two Haye's punches had the more noticeable effect on the few occasions he did land with anything. But after all the talk, the pressure was on Haye to deliver something brutal and sensational, and of course he failed.
BUT.....Vitali's movement is nowhere near as good as Wlad's, and his balance which was never great, is woeful now. He's also slower than Wlad of both hand and foot. Haye can certainly find the target much easier against Vitali, and Vitali will be more aggressive than Wlad, so Haye will get more opportunities to counter. Yeah Vitali has a much, much stronger chin than his little brother....but he won't just walk through flush punches. He backed away from Chisora when Delboy landed and Chisora isn't really a major league banger.
Stylewise....Vitali might in fact be the easier Klitschko to fight for Haye, especially at this point in time cos Vitali is fast fading. I think Vitali will still want to fight Haye, but i'm not sure Boente fancies it for his man. Better to just freeze Haye out, than risk a guy he hates getting Vitali at the right time and doing a number on him.
It wouldn't surprise me to see Vitali retire without ever fighting again. He looked a very weary old fella at the of 12 rounds with Chisora. Does he really need this anymore?
