None of those four represent a real threat to Wlad imo. Brock already got his ass laid out, as did Byrd. That leaves Chambers and Povetkin. Chambers is another Chris Byrd, good skills but too small to challenge Wlad and Povetkin is probably too early in his development.

The most difficult fight for Wlad imo outside of Sam Peter is Tony Thompson. At 6 ft 4 he's big enough, he's got the skills and he has the fight experience.

I'd rather see him get a shot ahead of those 4 other guys especially seeing as two of them have already had their chances and the other two are still only prospects at present,

Thompson is 35, been around a while and has earned his shot.
