I'm going for Haye to fell the Giant, Povetkin to stop Wlad and Vitali to stop Arreola in a brawl.

So

Haye
Povetkin
Klitschko

I'm gonna stick with Povetkin as I have watched his career grow from the 1st steps and with Teddy Atlas training him and bringing something extra to his game, then, I see him upsetting the jab of Wlad and once that is gone there is nothing there-just a chin waiting to be broken.

I can see Arreola winning but the Walker fight sent alarm bells out - especially as Travis got Ko'd again recently (and early). Vitali is like an old champ, who while on the slide still does things good enough against the right opponents. Still Vitali for me but if Arreola is there after 6 rounds then it could be good night Klitschko.

As for young David?, well he is against "The Beast" a man that Vitali won't fight. Pick and move is the plan abit similar to what Chagaev did only Haye is throwing those H-Bombs. Timber big fella Timber.
