Hitting the canvas 11 times, against 6 different oppenents, and getting TKO'd 3 times, I dont know about you, but it just screams glass to me.:yep
In my humble opinion i have to say Wladimir.. I like Sultan and Sammy equally (regardless of the McCline showing) Ruslan Chagaev selected an opponent that made him look ordinary and i can only rate them on the current performances.. Peter v Wlad is a natural rematch in 2008.. It may be a deciding factor.. Maskaev, needs work .. and Povetkin has to grab a slice, he may be the major sleeper.. he did great against the underrated Chambers last week.. He is super talented , There are a lot of ignorant cats out there.. they can't see Povetkins skills..
Wladimir is not an easy fight for any Heavyweight in history. That doesn't mean he beats all, just that he gives anyone of them a tough fight.
I think his chin would give out on me against the guys I named, but he would manage to grab a title somewhere down the road, maybe against a guy like Morrison or Seldon.
