This is ingnoring the fact that Froch is also at his best when an opponent is in front of him. I see this fight being very similar to Froch vs Pascal.
Since the Ward fight highlighted some limitations I'm really not sure on this. Before that I would have easily said Kessler by UD but Kessler looked physically weaker and his body looked somehow different like he'd lost muscle mass and he proved to be not as strong as I thought he was. I think I'm edging towards Froch. He's limited but specialises in finding a way to win
This is going to be a war of attrition. I see Froch standing on Kesslers toes and dragging him to somewhere he'll find he no longer has the appetite to be. Kesslers work up close was poor against Ward and I see froch coming through to outstrength and outwill him around the 9th/10th. Those cuts could also be a factor again.
