1. Fedor - undefeated for 10 years and fought the best the HW division had to offer.
2. GSP - Has avenged every loss he has had and has made beating world class Top 10 P4P fighters look insanely easily.
3. Silva - Has been the MW kingpin since 2006 and looked just about unstoppable during that run.
4. Hughes - Most dominate champion in the history of MMA. 7 title defense, 6 stoppages, 3 in the first round.
5. Hendo - Maybe the most accomplished on this list with winning tournys and holding titles in just about every major MMA org that has ever existed.
6. Liddell - Arguably the best LHW of all time. Never went the distance in a title fight and KO'd a who's-who of MMA during his era.
7. Wandy - Right up there with Liddell, would be higher if his record was not filled with cans.
8. Jones - No one can ignore the run he has been on. If he can keep this up he will break into upper level.
9. Aldo - Arguably the best fighter to ever step into MMA under 170 pounds. Has basically looked unstoppable over the past few years.
10. Cruz - Can make an argument he is the best fighter to ever fight under 170 pounds. Has avenged his only loss and if he had more finishes would be higher on the list.
Greatest of All Time
