KO both Klitschkos hell peter had his hands full with a short,fat Middleweight.I see him having a tough time with any of the top ten in the WBC,WBA,IBF and WBO.His chin and power got him this far now he has to box and we all know when he gets tagged a few times he reverts back to his old style.
Most everyone would have problems with one of the best defensive fighters of all time. You're not being very even handed, dude. And unless Peter really improves his boxing and defensive skills, I don't think he has a shot of either of the brothers unless he catches them with a blow they don't see coming.
