For a bit of fun. Can you start at heavyweight and list your way down through the weights based on x fought y, y fought z, etc. Example (using weight jumpers which is kind of cheating): Ruiz fought RJJ RJJ fought Hopkins Hopkins fought Pavlik Pavlik fought Martinez Martinez fought Margarito Margarito fought Pacquaio Pacquaio fought Sasakul Etc. I'll try to do one covering all divisions in a while (not jumping about 30lbs with the Hopkins and Pacquaio examples above)
I'll just do the original 8. Ali fought Moore Moore fought Eddie Booker Booker fought Fritzie Zivic Zivic fought Sammy Angott Angott fought Willie Pep Willie Pep fought Manuel Ortiz Ortiz fought Jackie Jurich
