Romero has been extremely competitive despite his losses. Since Costa is out, he's the logical choice for the next person in line. I'd rather have Costa fight, but he's out and there is nothing we can do about it.
Aldo looked great at BW, and put on a great performance that he should not have lost.
Aldo vs Moraes:

They aren't going to sell a Moraes rematch with Cejudo since he just lost to him. I can understand why people feel that Aldo doesn't deserve it, but it'd make for a much better match than a rematch with Moraes.
As for Conor...
Conor got destroyed in his fight with Khabib. He got knocked down, and tapped out. He managed to do nothing with an entire round in his favor (standup only)
The best strike Conor landed the whole fight was an illegal knee.
He cheated the entire fight by hooking gloves, holding shorts, and holding on the the cage with hands and feet. I think the count was up to 19 times that he cheated.
Ferguson is on a 12 fight win streak. Gaethje is on a 3 fight win streak. Both fighters beat Cerrone before Conor did.
Since Cerrone has been back at 155lbs, he has wins over current #15 ranked Hernandez, and #9 ranked Iaquinta. Cowboy hasn't done shit at 155lbs since being back. Not impressive at all, and not worthy of a #5 rank. He's highly ranked only to make Conor's win look better.
Conor took the sloppy seconds and chose to fight a guy on a 2 fight KO losing streak.
Conor had the choice of any fighter on the roster since daddy Dana gives him what he wants, but he chose 2 fight KO losing streak Cowboy over actual legit contenders.
So how the fuck do you justify Conor getting a shot over more deserving fighters?
Romero is way more deserving, and so is Aldo.
Conor had his chance to pick a legit contender and pussed out like a bitch. He doesn't deserve a title shot until he beats someone on a winning streak thats worth a damn.
