I see it going like Bryd/Holyfield did, with Holyfield looking his age and missing alot. I cant see Holyfield out boxing Iggy, unless Holyfield catches Iggy with something big I cant see Holyfield doing well.
I don't know. I haven't seen a lot of clear footage of Povetkin, and he's often on the offensive, but from what I have seen he does move side to side using his waist/hips to move his trunk. I'd like to see the Donald fight again to get a gauge of this.
