best case for me is aldo/yair.
Aldo never fights, man. He's always pulling out with something or other. I mean, how many times has he fought over the last 5 years? Probably around 10, right?
Plus Aldo got knocked out by Conor. And even if they rematch, Aldo isn't going to win. I don't think Holloway will win a rematch against McJesus either, but he's got a more believable chance.
If Aldo ends up the undisputed champ the division is going to tank. Let's not even mention the fact that the guy can't sell a PPV.
I get what you're saying with best vs. best, that's why I'm hoping Aldo isn't the best...
