Former K1 fighter Ustinov looks quite good right now.Two or three big wins will catapult him into the group of the most interesting and promising fighters out there.
As has been said, Ibrag and Chagaev are both top heavies who are far from done. In my opinion.Chag has yet to be beaten, and Ibrag has but one loss.
Chagaev I agree, I'm hoping to see him regain his old form again. Ibragimov has been horribly negative in three fights now - Briggs, Holyfield, Wladimir, and he fought basically the same way against all of them. I'm concerned he may have, like Ruiz did, decided this is a style which works for him and will now stick with it. I'm neutral, bordering towards thumbs down on Ibragimov at this moment in time. He's in danger of becoming the opponent that no-one will want to fight because he's tricky and he's dull.
Thompson and Maskaev are still capable fighters. The up-and-coming Zimbabwe born Londoner Derek Chisora is showing some talent and maybe a treat for the future -a possible heavyweight showdown featuring UFC former-Champion Andrei Orlovski as stated by Freddie Roach (during Andrei's training for his January showdown with Fedor Emelianenko). Get some of these fighters together and we could see real fireworks in the Heavyweight division.
Klitschkos are the very best. Chagaev is good fighter. Dimitrenko Ustinov is coming along. Povetkin, who beat the crap out of Chambers, good fighter, but will lose to Vlad. Arreola is best American heavyweight. There are more new heavyweights for future also.
Oh, forgot to include Valouev, he has been underrated due to bias. We will see tomorrow how good his is, but he has beated some good fighters, will lose to Vitali though.
