Froch couldn't that's for sure, he would be destroyed by Beterbiev, far too open and hasn't got the whiskers to take the shots.
Beterbiev all day. He matches up favorably against all of the advantages Froch typically had in his favor. Artur wins by late round stoppage.
Froch has average defense at best. He can be outfought and outboxes. He needs too much time to set up his big shots. I honestly think it would be like throwing a squirrel in to a wood chipper. I think Beterbiev just too strong, too mean for a guy like froch
