This is going to be nearly impossible. But I guess that's the fun. Here are the rules. Anyone who had a significant chunk of there career from 1970 on counts (1970 was when I remember watching my first fight, Ali-Quarry). Here is the criteria I'm basing things on
1. Great fighters defeated (preference for them being in their prime and at their best weight)
2. Dominance in multiple divisions, taking on all comers
2. Dominance in a division, taking on all comers
4. THE MAN championships
5. Other extraordinary accomplishments
6. Extraordinary displays of fighting spirit (hey, it's my damned list!)
---------------------------------------------

1. Muhammad Ali-Defeated the greatest heavyweight roster in history. Liston, Frazier, Foreman, Patterson, Norton, Folley, Bonavena, Lyle and Shavers. First three time lineal heavyweight champion. 19 defenses. The first big, highly mobile heavyweight.

2. Roberto Duran-Defeated Ernest Marcel, Ken Buchanan, Esteban DeJesus, Carlos Palomino, Ray Leonard, Pipino Cuevas and then as an old man Davey Moore and Iran Barkley. 12 defenses of lightweight crown. Defeated atop three all-time 147 in his prime to become undisputed king there too and fought a top five all-time middle to a standstill. Arguably had two HOF careers, before and after No Mas.

3. Ray Leonard-Defeated Tommy Hearns, Wilfredo Benitez, Roberto Duran and Marvin Hagler. That's as good a top four as maybe anyone in history. His durability and overall activity levels keep him from being higher. A true great.

4. Pernell Whittaker-THE MAN at both 135 and 147 with a total of 18 defenses. Schooled Azumah Nelson and Julio Cesar Chavez. One of history's great defenders.

5. Ruben Olivares-THE MAN at 118 and 126. He ruled the greatest bantamweight era in history defeating Castillo, Medel, Burruni, Rose, Pimintel and then went to 126 and knocked off Chacon (twice). The finest bodypuncher I've ever seen.

6. Julio Cesar Chavez-THE MAN at 135 and 140, defeated Meldrick Taylor, Edwin Rosario, Hector Camacho, Juan LaPorte and Ruben Castillo. 16 defenses.

7. Carlos Monzon-THE MAN at 160 for seven years and 13 defenses. Beat HOFers Benvenuti (twice), Griffith (twice) and Napoles as well as Rodrigo Valdez. Closed his career with a 13 year, 70+ fight unbeaten run.

8. George Foreman-Really hard to rank. He destroyed Joe Frazier twice and Kenny Norton and had a slugfest with Ron Lyle. He's here for a simple reason. He did the impossible. He won the heavyweight crown 21 years apart.

9. Marvin Hagler-Dominated 160 like perhaps no one in history. Won every one of twelve defenses by KO except Duran. Defeated Briscoe, Watts, Antuofuermo, Duran, Hearns and Mugabi.

10. Manny Pacquiao-First man ever to win four lineal championships. One of the few in history to excel across five of the original divisions. Not higher because many of his biggest wins were against men no longer at their best weight or in their primes. Could well move higher.

It Kills me, KILLS ME, that Ricardo Lopez, Alexis Arguello, Jose Napoles, Mike Spinks, Evander Holyfield, Roy Jones, Chiquita Gonzales, Wilfredo Benitez, Khaosai Galaxy, Tito Trinidad, Azumah Nelson, Salvador Sanchez, Carlos Zarate, Erik Morales, Tommy Hearns, Eusabio Pedroza, The Bodysnatcher, James Toney, BHOP and Rafael Marquez aren't on this list. But I only had ten slots!

Who did I leave out and where am I wrong?
