FEATHERWEIGHT DIVISION (UP TO 145 POUNDS)
1. Max Holloway (19-3)
Five months after taking the title away from Jose Aldo in Brazil, Holloway doubled down on his title reign by knocking the all-time great out a second time. Make it 12 wins in a row.
2. Jose Aldo (26-3)
Aldo certainly didn't look bad at UFC 218, but he also didn't look like he could beat Max Holloway if they fought 50 more times. His reign as the best featherweight in the world is seemingly over, but what a run it was. What's his next step?
3. Frankie Edgar (22-5-1)
How about that? Not that anyone was really writing off Edgar prior to UFC 211, but they were sure enamored by his young opponent, Yair Rodriguez. Edgar proceeded to stomp Rodriguez into the ground for a TKO victory. Sorry if we even considered doubting you, Frankie.
4. Cub Swanson (26-7)
In 2014, Swanson's budding title run came to a sudden halt when he suffered back-to-back losses to Frankie Edgar and Max Holloway. That feels like a long time ago now, as Swanson has rebounded with four consecutive wins. He has won 10 of 12 and is firmly back in the title picture.
Next: UFC Fight Night on Dec. 9, vs. Brian Ortega
5. Ricardo Lamas (18-5)
Prior to UFC 214, Jason Knight was starting to garner a lot of attention. Lamas reminded everyone just how good he can be in that fight, dominating Knight in a first-round finish. That's two very impressive wins for Lamas in his last two fights.
Next: UFC 218 on Dec. 2, vs. Jose Aldo
6. Patricio Freire (26-3)
Pitbull is once again Bellator's 145-pound champ, as he submitted Daniel Straus via guillotine choke in April. Since 2013, Freire has only one loss in this weight class -- a five-round decision to Straus in 2015.
Next: Bellator 188 on Nov. 16, vs. Daniel Weichel
7. Chad Mendes (16-4)
Coming off a first-round knockout loss to Frankie Edgar in December 2015, Mendes was hit with a two-year suspension for violating the UFC's anti-doping policy. It will be at least 2018 before we see Mendes in the Octagon again.
Next: UFC 205 on Nov. 12, vs. Jeremy Stephens
8. Yair Rodriguez (10-2)
Whoa ... Rodriguez looked like the next big thing going into UFC 211, but it's back to the drawing board he goes after being crushed by Frankie Edgar. It's worth noting, however, that it was Frankie Edgar. Rodriguez might still be the guy we think he is. It just might take a little longer than we thought for him to reach the top.
9. Chan Sung Jung (14-4)
It seems remarkable that Jung would be able to step away from the sport for more than three years and return to the top 10 rankings so quickly. But that's exactly what's happened. Jung was a title challenger when he stepped away to serve his mandatory military duty and he came back in style with a first-round knockout over Dennis Bermudez.
10. Brian Ortega (12-0)
Ortega is a young featherweight, whose best years are still ahead of him. He's been fighting professionally since 2010, and still doesn't have a loss to his name. There's definitely been adversity, including his last fight against Renato Carneiro, but Ortega keeps finding a way. His next test, Cub Swanson, is a rather big one.
