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. Brian Ortega (13-0)
There's new blood in the UFC's featherweight title picture! After years of dominance by Jose Aldo, this division was looking at a mix of familiar faces, but finally here comes a new one in Ortega. He's perfect thus far in the cage, and a finish over Cub Swanson has him firmly on the map at 145 pounds.
5. Cub Swanson (26-8)
Swanson believed he was this close to his long-awaited UFC title shot in December, but a submission loss to Brian Ortega will set him back quite a bit. He's not out of the picture by any means, but for a guy who has waited so long without a title shot, any set back must feel like a major one.
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. Josh Emmett (13-1)
Emmett has surged quickly into title contention since making his UFC debut in 2016. His latest performance, a first-round knockout of Ricardo Lamas on short notice in December, was a major eye-opener and sets him up for big things in 2018.
8. Ricardo Lamas (18-6)
It was a wicket set of circumstances surrounding Lamas' knockout loss to Josh Emmett in December. He was supposed to face the former champion in Jose Aldo. The fight was changed, and then Emmett missed weight. It's the kind of loss you hate to see for Lamas, who had been on a two-fight win streak.
9. 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
10. 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.
