Fights that were either planned (at least negotiated if not signed) or strongly rumored/in demand that fell apart or never materialized (but please, let's keep it reasonable - fights that were not only realistic but very plausible at the time) that you'd desperately like to turn back time to make happen: For me: Guzman-Katsidis Lewis-Bowe Jones-Michalczewski Mijares-Montiel Quartey-Mosley Hopkins-Toney @ MW Tapia-Hamed Mosley-Trinidad Mayweather-Spinks Cotto-Hatton @ 140 Calzaghe-Johnson Casamayor-Freitas II De La Hoya-Wright Tyson-Ibeabuchi I'm sure I'll think of more...:think
