I was gonna say name just 1 fight in each division but I thought... there`s just too many great fights in boxing`s long history to keep it at just 1. There are no rules, as long as both did or could have fought in the divisions you choose..... 122 lbs - Gomez v Morales ----- Hamed v Pacquiao 126 lbs - Sanchez v Pep ----- Hamed v Morales 130 lbs - Arguello v Chavez ----- Delahoya v Mayweather 135 lbs - Duran v Chavez ----- Duran v Whitaker 140 lbs - Pryor v Chavez ----- Mayweather v Whitaker 147 lbs - Robinson v Leonard ----- Robinson v Hearns 154 lbs - Hearns v Trinidad ----- Leonard v McCallum 160 lbs - Hagler v Robinson ----- Hagler v Monzon 168 lbs - Jones v Hearns ----- Toney v Calzaghe 175 lbs - Spinks v Foster ----- Conn v Moore 190 lbs - Tunney v Holyfield ----- Marciano v Holyfield HWT - Ali v Louis ----- Frazier v Marciano There were loads more in most divisions & it was really hard just to name 2 but there you go. :good
