This is only for what they have done to this point. Not what they could do or will do in the future.
7.
Cain Velasquez. He's undefeated during his short career and hasn't really been put into too much danger (besides a few big shots from Kongo). The reason I have him last right now is because beating an over the hill Big Nog and a green champ in Lesnar isn't going to put you high on this list. Yet. Like I said, if this list had anything to do with potential Velasquez would be no where near number 7.
6.
Frankie Edgar. I love Frankie Edgar, he's one of my favourite fighters and he's a champion any organization should be proud of. He dethroned the lightweight king and then dominated him in the rematch. And then he went to a draw with a guy that a lot of people thought would win the fight. The problem with all that though is that he's still so new to being a champ. When he beats Maynard (yes, I said WHEN

) then he would move up on this list but to this point the other champs have one up' d him.
5.
Jon Jones. He may not have defended his title yet (he hasn't had the chance to) but he just dominated arguably the best LHW in the history of the sport, and not only beat him but dominated him in every aspect of the fight and is the first person to make him him tap to strikes (Yes, we all saw it as much as it pains me to say it) or even come close to making him think about tapping to strikes. That alone puts him ahead of both Velasquez and Edgar. If this was about potential Jones could very well be number 1 on this list. Ask me again in a year and we'll see how high he jumps.
4.
Dominick Cruz. To this point he's beaten every bantamweight put in front of him, and that includes the top fighters in the division (Benavidez, Bowles and Scotty Jorgensen). It'll be interesting to see how he fairs against the only man to ever defeat him in Urijah Faber. If he can avenge that loss it will definitely boost his career and popularity in the ufc but I still wouldn't see him any higher on this list with the likes of the top 3...
3.
Jose Aldo. At this point in the list we're talking about the elite of the elite. They can very well be switched around at will but I'll leave that for others to debate. Aldo came into the WEC and instantly made his mark. He's a ko machine and it doesn't matter how good you are, Aldo is going to make you look like an amatuer (just ask Faber). With wins over Mike Brown, Urijah Faber, Manny Gamburyan and Cub Swanson there is just no stopping this guy. He has his hands full with Hominick but I mean the question of this fight isn't if Hominick can pull the upset, it's how long can Hominick last...
2.
Georges St.Pierre. The list of fighters on this guy's resume is probably the most impressive I've ever seen. The only reason I have him as number 2 is because he has had those stumbles in championship fights before (even though he's avenged them both very impressively.) Let's think about this for a second. Matt Hughes (2x) Matt Serra, BJ Penn, Jon Fitch, Thiago Alves, Dan Hardy and most recently, Josh Koscheck. I mean who else is there?
1.
Anderson Silva. And here we go, number 1. It's hard to argue against a guy that has never been defeated in the octagon and has fought some of the best there is while setting ufc records. He's had some questionable title defenses and performances but he still came through every single time. He's beaten Hendo, Sonnen, Franklin (2x), Maia, Marquardt, Belfort and others. Like GSP he's beaten almost everyone there is to beat.
And there we go. Thanks SpicyMeatball, that was fun.
