Guys much worse then Eddie Chambers have won heavyweight titles in recent years. Chambers has one of the better skillsets in the division but absolutely no size to match.

Anyways, there are only 4 people I would even be mildly interested in seeing face Wlad.

Povetkin
Solis
Haye
Vitali

Obviously he's not fighting Vitali. Povetkin is to slow and small probably. Solis would be interesting but he's a pretty big unknown at this point. And Haye I think we know who he is. He miiight have some speed to trouble Wlad but I doubt it.
