The Nate Diaz fight was FOTN as well, the only FOTN he won.
Guida was constantly trying to pass guard against Hioki, Hioki is just a beast off his back. Clay actually got Pettis back at one point and worked for a few submissions.
Clay is trying to advance position and due to his recent submissions, if he was able to pass guard, he may pull it off. He's just always fighting the best of the best, most who are better than Clay technically.
There are many paths to freedom....not all are peaceful.
