Joe will not come out of retirement. He can just sit back and wait for another top quality opponent to take Froch out sometime soon (Taylor was almost that man) and then he can enjoy his retirement knowing he got out at the right time. Froch is a poor, sluggish boxer with no defence who isnt getting any younger. It's only a matter of time before somebody beats him. I want Froch to fight B-Hop next. B-Hop, the master of defence and counter punching wont believe his luck when he's staring at a boxer who doesnt even move or defend himself.
Froch is slow as hell, it would be on of the easiest Joe fight. If Joe can give a boxing lesson to Kessler, it would be very ugly vs Froch.
