Let me be clear: The question is: What are some famous names (CONTENDERS ONLY, NOT CHAMPIONS) whose biggest career achievement was a loss rather than a win? Include only those contenders which this applies to. The question IS NOT greatest to never win a title. here are some guys i got to start us off: -bonavena's great efforts in his losses to ali & frazier -golota fighting good enough to beat bowe but losing by DQ -firpo knocking dempsey out of ring in a heck of a loss -Joe Roman's L to Foreman but becoming 1st Puerto Rican to fight for piece of hw crown -Yaqui Lopez's L to Saad in 1980 Fight of the Year do you agree with my list or certain parts of it? please indicate which. of course i won't mind if you disagree with my choices. please add your own too. the point is we all have a good discussion here.
