Hi Luigi, Heres my take - Billy Miske had a much better chin, better combination puncher and fought & beat tougher fighters. Miske also gave Dempsey a few tough rounds as well!!! Bobo Olsen had a powerful punch, but his chin was not the best. Sugar Ray Robinson and Archie Moore both destroyed Olsen. I think that Miske would outbox Olsen in the early rounds and stop Olsen in the mid-to-late rounds. Grebfan9 www.firstroundboxing.com
