He's not the same fighter. Froch has more skills but doesn't have Andrade's chin. Froch is not as active as Andrade neither. Froch likes to wait and counter. We saw tonight that if he's behind, he can do the job, which is worth respect.
Andrade and Kessler are the two guys I see Froch having problems with. Froch will go as far as his chin and his power take him. His power won't get him anywhere against either of these guys. And they are both strong enough to take him out.
