Well I guess what I'm saying is it all comes down to how much weight you give each bit of criteria, either positive or negative. I'm willing to let Wlad's clearly suspect (though I wouldn't say glass) chin slide a little more than you, in that I don't think it's bad enough to drag A+ ability out of the A range. A-, sure. Chin is a small criteria. Then you have a guy like Peter, whose "heart" and vaunted "power" (which is okay but unspectacular) I am not willing to reward as much as others (who I can only imagine turn a blind eye to his deficits because heart and power in the HW division gets people irrationally excited) in the face of his lack of everything else.
Peter is still young and has a lot to offer in the division. He's not the best fighter out there without any doubts but he's not an easy target either. He brings entertainment to a division that lacks it, why hate that? He's my current favorite(has been for a long time) Heavyweight and I'm looking to enjoy his fights instead of insult. There are far too many good fights he could be involved in. A rematch with Wladimir, Chagaev, Valuev, Haye, Brewster....etc, anyone Peter fights is going to be exciting and that's more than enough. Just hoping he'll come in great shape for every fight(I know it might be a bit too much to ask for, considering how he comes out of shape sometimes) but I'll be hoping he does and will continue the support.
I wouldn't say chin is a small criteria. It can completely undermine the rest of your work, and has done on a number of occasions for Wlad. In combination with his lack of confidence, it is a big factor, because it means he has to fight ultra-cautiously. This isn't a personal stylistic criticism, but rather he puts in a lesser performance than I believe a true A like Lennox Lewis would against similar competition. Ibragimov for instance, no way he lasts 12.
Iggy would get blasted out in less than 6 with Lewis, the guy was on ***** street against journeymen Ray Austin in there fight a few years back. If you watch the Wlad fight closely, Wlad landed very few rights, and the first decent one that got through the gloves made Iggy's legs collapse from under him, Wlads cautious ways and lack of killer instinct kept Iggy in that fight the whole 12 rounds.
I'd say hes at least B-/B because he has a lot of intangibles going for him like Size/Punching Power/Chin etc. His skill may be C level but other factors go into a fight and hes got a lot of Pluses in those categories. And he is a secretly James Toney's biggest fan.
