For startes, he's only fought one decent opponent in the UFC and that was Clay Guida. Second, he was getting absolutely owned for 2+ rounds including being brought to a point where another ref could've stopped the fight. Huerta himself admits to going black for a moment. Admittedly, Huerta is tough as nails and managed to find a way to fight through it, so I'll give him that, but he is technically nothing special.

Which is why Florian is a bad match-up for him. Huerta gets the edge in athleticism, but that's it. Florian is super tough, has fought better opponents, and is technically much more sound. Yeah, his boxing is only ok, but his kick boxing is terribly underrated, his wrestling is significantly improved (particularly in the takedown department) and his BJJ is miles ahead of Huerta's...particularly his guard passing. I do not believe Huerta can stop Kenny from passing his guard and that could well be his undoing. Moreover, for a fighter reliant upon his wrestling, he could do almost nothing to stop Guida from taking him down at will.

People call Huerta "unorthodox", but there's nothing special about him. He initiates scrambles, which can be deadly against someone with great BJJ (Crane could've made an account for himself with better cardio and improved toughness). His hands are ok, but who has Huerta clapped with his punches? Huerta is scrappy and athletic with decent technical level, but that's it. He isn't terribly difficult to figure out as a fighter and doesn't train with a team known for their technical prowess.

And even if Florian isn't the man to beat him, please believe Sherk, Penn and Stevenson would have their way with him.
