Edgar is a good pick for number one. A featherweight that could move up and beat the LW champion (Ben is my favorite fighter, but the second fight was close enough that Edgar is still arguably the champ)
Hendricks is also a great pick. The guy has a better win streak right now than the champ of his division lol. And let's face it, p4p should mean the guy who can demonstrate great skills against people bigger than him, and Hendricks is a puny welterweight compared to most of the guys at his level.
Urijah Faber has to be on this list dude. He'd could move back up to featherweight and beat almost everyone imo. Not Aldo obviously, and Edgar would outscore him, but i mean, c'mon, look at the dude's resume.
A lot of people have JDS in their rankings. I think that's fair. The guy is so far above most of the division. So dangerous, yeah, regardless of weight, that is terrifying.
Poor Machida and Rashad. Two of the top 3 light heavyweights and they really should be middleweights. They deserve spots on this list.
Jon Fitch imo deserves a spot. Just for being Jon Fitch.
And I'm gonna put Sonnen on the list too. There's not a ton of logic for this placement, I just think the guy is one of the toughest almost-champs of all time.
