Vitali would have flattened him. If Povetkin had been in shape for the fight he might have possibly stopped Huck in the later rounds. Sasha was hurting from the fifth round on. Maybe Teddy isn't the greatest trainer in the game, but at least when he's training Povetkin he shows up in shape.
I doubt Huck would land much. Beyond the rabbit shots, Huck was only able to land significant punches because Povetkin was ill-conditioned and tired.
