Good boxer, mean left uppercut but lacking defense and especially inside work. Froch was all wrong for him, took his shots and still came forward, Bute wasn't prepared for that. He would have given Ward problems. After he knocked out Andrade he tried to become a one punch KO artist. The Early version of Bute was better, southpaw with power and high ouput of punches.
Don't take this analogy too far, man. Effing Froch and Kessler certainly aren't Foreman and Frazier either, with respect to everyone involved.
