I'll start it off with : oldest major title holder - Bernard Hopkins - took record from george foreman when at age 46 when he beat pascal . later broke his own record , most recently at age 49 champion at most weight classes - Manny Pacquaio - 8 divisions first and only ever fighter to hold 2 major titles in each of 2 weight classes simultaneously - floyd mayweather jr :bbb
Evander Holyfield - only fighter to become undisputed champion in 2 weight classes - doing it at CW and HW using the following criteria: http://en.wikipedia.org/wiki/List_of_undisputed_boxing_champions :bbb:bbb
Edwin Valero 27-0-0-0 (KO 27) most enduring legacy of Valero :boxer #1 Highest KO ratio for a champion (Wilder will break it) #2 Highest KO ratio champion in two divisions (Will be around for a while)
ATG Edwin Valero > ATG Rocky Marciano There is no restrictions on how high we can rank Valero, based of Sanchez, Pacman & Marciano ATG ranking We can't be sure to deny Valero cleaning up 5 divisions 50-0-0-0 (KO 50) Champion :boxer No Valero = No Marciano = No Greb = No Sanchez :nod
