When fighter suffers plenty stoppage L's he's often named 'glass-jawed'. But that's not always the case Bert Cooper is one of these. The guy surely could take a punishment, he showed heart and chin against prime Mercer and Holyfield, he was very exciting and game. But Cooper was stopped many times. He quit sometimes (Foreman, Williams), he was battered in other losses, but he never had signs of 'glass chin'. Not even late in his career. Name other fighters witn decent or good chins who were stopped many times
