Chael isn't an elite MMArtist, he's got great MMA wrestling, but that's it. And his body of work is distinctly mediocre.
Alistair's loss was a long time ago.
Fedor is the odd one out. I think he started believing his own press, and it cost him.
Either way, Toxic has a point. Submissions from the bottom are still happening even at a high level, but they're getting rarer. And Rory is very unlikely to get caught.
