Im pretty sure a confident , motivated Calzghe gives Johnson a thrashing . Rememeber the yank was nothing more than a journeyman in his youth but his had sucess near the end of his career by taking the right fights at the right time

Clinton didnt have the workrate to match Glencoffe but he held his own . I reckon Joe would steamroller him with his workrate and pace . Not sure about a K.O but it would be too different to the Lacy fight
