Kenny Florian (Submission of the Night), Roy Nelson (KO of the Night) and the duo of Ross Pearson/Dennis Siver (Fight of the Night) pocketed $30,000 bonuses for their work on last night’s UFC Fight Night 21 event, but what’s money compared to the numbers of the Potato Index? Sure, maybe the Index’s arbitrary numerical rankings system can’t be exchanged for goods and services, but on the flip side, no one has ever accused the Index of being the root of all evil. Not yet, anyway.

Let’s see who’s up and who’s down on this fine Thursday morning.

Kenny Florian +74
Beating Gomi doesn’t mean quite as much as it once did, but Florian looked sharp, patient, and smart in victory. He probably still wouldn’t beat B.J. Penn, which makes him the second-best lightweight in the UFC. Guess it’s better than being the third-best.

Takanori Gomi -31
Honestly? He did better than we expected. Florian picked him apart with that jab and he seemed to get frustrated enough to start looking for the one-shot home run, but at least he looked competitive against a high-level opponent. Now let’s see him against someone in the middle of the pack so we can find out just how much fight he has left in him.

Roy Nelson +86
What, you thought “Big Country” was in trouble just because he was giving up nearly a foot in height? Naw, playa. Struve was just the right height for a looping right hand, and a guy with that much gut behind his punches doesn’t need to land more than one of those. James Toney next? That’s a suggestion we could get behind, even if it was intended as a joke.

Stefan Struve -72
Tough kid, bright future, but he’s obviously not there yet. The UFC should think of him as more of a work in progress with a lot of potential upside down the road. Once he learns how to most effectively use those long limbs, he could be trouble.

Jorge Rivera +63
How is it that, at 38 years old, Rivera now seems to be hitting his peak? Not that he set an incredibly high standard to beat in his twenties, but suddenly the dude went from just hanging around to hurting people. Milford, what!?

Nate Quarry -57
No one will question his heart or toughness, but once again we see him undone by a disturbing lack of head movement. Anybody is going to fall eventually if they become such an easy target.

Ross Pearson +58
The Brit continues to impress with sharp striking and an intelligent approach. If he keeps improving at this rate he’ll break into the top of the division in no time. We wouldn’t mind seeing him tested by someone who’s already there in his next fight.

Dennis Siver -44
He can take a beating and still keep coming, but once he has to go to plan B he seems lost. The spinning back kick is a nice little move to have in your pocket, but against the better guys in the division it’s not a fight-ender.

Gleison Tibau +47
It was only his third TKO victory ever, and his first in nearly three years. What he lacks in frequency, though, he makes up for with sheer brutality.

Caol Uno -49
You won’t find a nicer guy in this sport, but it’s starting to look like his best days are in the rearview mirror. We’d rather not have to watch him staggering around the Octagon for too much longer if that’s really the case.

Bojangles Coliseum -121
A power outage in the middle of the event? Sure, it provided Joe Rogan with the opportunity to make an Arianny Celeste vibrator joke on Twitter, and that’s fun, but come on. Let’s act like professionals here.
