We’ve all spent considerable time during Jon Jones’ six-and-a-half year run in the UFC trying to figure out if he is a good man or a bad man.

In the wake of news this week, via Steven Marrocco of MMAJunkie.com, that the fight company's brilliant but often perplexing light heavyweight champion checked into a drug rehabilitation clinic after failing a Nevada Athletic Commission test for the primary metabolite for cocaine, perhaps we can finally agree to meet in the middle.

Jones, it seems, is just a man with as much capacity for weakness as greatness.

As the announcement floated across our social media timelines on Tuesday afternoon, it was met with equal parts surprise and studied indifference. As all things involving Jones, there were a lot of bad jokes to be cracked.

MMA Kingpin is a funny responsibility. It's an entirely fictional position, sure. But it's one with no small level of import. Filled by a single fighter at a time, it's the man with the combination of accomplishment, skill and pure swagger that makes him, unmistakably, the sport's top dog.

For most established sports that's not a big deal—baseball is still baseball, no matter how classy Derek Jeter is or whether Yasiel Puig is hustling enough on the way to first base.

But for MMA, a sport still being introduced worldwide, the man on the throne makes a big difference. It means, like it or not, the Kingpin sets the tone for what mixed martial arts is and what it might be. He represents all of us and our sport. 

After Saturday night's humbling of Daniel Cormier at UFC 182, Jon Jones sits alone at the pinnacle—but it's a seat still warm from the seven years Anderson Silva reigned with such grace and impish vitality, a strange combination, but one he pulled off with style.

For the last six months, they were the best of enemies, and on Saturday at UFC 182, Jon Jones and Daniel Cormier pretty much proved to be perfect dance partners, too.

Jones got the last laugh—retaining his title and sending the 35-year-old Cormier spinning into uncertainty with a unanimous-decision win—but not before the challenger brought out the best (and worst) in the polarizing light heavyweight champion.

It was fitting that their intense personal feud ended with a fight as emotionally charged and layered as the bad blood itself. Also, that the two did not immediately kiss and make up afterward.

"The respect just wasn't there,” Jones told Fox Sports 1's Brian Stann after the judges awarded him victory (49-46 x 3). “I don't like Daniel Cormier. I don't respect Daniel Cormier. I hope he's somewhere crying right now."

UFC light heavyweight champion Jon Jones (21-1) is the best fighter in the world. If that was a controversial statement before he dispatched undefeated Olympian Daniel Cormier (15-1) by unanimous decision at UFC 182 on Saturday night at the MGM Grand Arena in Las Vegas, it's surely a given afterward.

It wasn't just that Jones, 27, beat Cormier, 35, a top heavyweight who dropped down a weight class to avoid a collision with his teammate Cain Velasquez, the heavyweight kingpin. It was the way he beat Cormier, half athletic god and half message-board troll, his two sides working together to create a truly memorable night.

"I don't like Daniel Cormier," Jones, who won 49-46, 49-46, 49-46, said after the fight on Fox Sports 1. "I don't respect Daniel Cormier. I hope he's somewhere crying right now. I'm sure he is."

To understand the level of animus in UFC 182's main event, you have to understand how the two men ended up in the cage in the first place. It's the story of giant egos, wounded pride and transcendent talents.

LAS VEGAS—In pre-fight interviews leading up to UFC 182, Daniel Cormier told Jon Jones that he hoped Jones would finally be the man who could be his equal.

He got what he wanted, and then some.

Through five mostly-thrilling round atop an otherwise lackluster UFC 182 card, Jones cemented himself as the best pound for pound fighter in the history of mixed martial arts by doing, once again, what he likes to do best: fight his opponents in their strongest area. On this night, that meant Jones became the first man to take Cormier to the canvas. And then he did it again. And again. And again.

Cormier was game. This loss wasn't a reflection of his own status as a mixed martial artist. He is clearly close to the top of the light heavyweight division. The problem is that Jones isn't even on top of the heap any more. He's in the stratosphere, looking down on a pile of ruined bodies.

LAS VEGAS — The Ultimate Fighting Championship has acquired the complete video libraries of eight of the most famous and respected mixed martial arts promotions in the history of the sport.

The libraries of Pancrase, Extreme Challenge, Cage Rage, Hook and Shoot, TKO Canada, King of the Cage, UCMMA and XFO are in the process of being secured and flown to the United States. From there, the tapes will be digitized and added to the digital subscription service beginning in the spring.

The announcement was scheduled to be made during a special media conference on Saturday afternoon prior to the start of UFC 182: Jones vs. Cormier.

In an exclusive interview on Friday afternoon, Zuffa Chief Content Officer Marshall Zelaznik told Bleacher Report that the success of the Invicta promotion led the Fight Pass team to explore new options for adding more content libraries. In particular, heavy usage of the Invicta library on Fight Pass indicated that hardcore fans, coaches and fighters around the world would be willing to utilize more hours of archival content.

This is the one we've all been waiting for.

After one change in opponent and a bevy of knee surgeries, light heavyweight champion Jon Jones will finally defend his title against Daniel Cormier on Saturday at UFC 182.

Are we stoked? Dude, we're more than stoked. What comes after stoked? 

If Jones-Cormier even halfway-kinda lives up to the hype, we might see Fight of the Year honors wrapped up during the very first event of 2015. The rest of the card ain't too shabby, either.

Controversy, as always, is swirling around Jon Jones (20-1). On Thursday, it was a hallway war of words. What it will be tomorrow, no one can say.

The UFC light heavyweight champion has managed to stuff a career's worth of drama into just a few short months in the lead up to his fight Saturday with two-time Olympian Daniel Cormier, a fight that will, finally, bring one of MMA's greatest feuds to a close.

The bad blood started years ago with Jones' offhand claim he could take Cormier to the mat. Cormier, a proud wrestling legend, was not amused. That was the beginning. But the two were separated, at the time, by a weight class and by promotional boundaries. Nothing came of it except simmering anger.

It began in earnest last August with a scuffle at a pre-fight media appearance, a dustup that included a tumble off the hastily constructed stage, a terrified UFC PR flack and even a thrown shoe.

LAS VEGAS — Of the many UFC "rivalries" over the years, 98 percent of them are fake, created out of thin air for the purpose of selling pay-per-views.

We have heard endless stories of fighters who hate each other, only to see them hug after the fight and admit they were just trying to sell it. Fans are jaded when it comes to these kinds of things, and rightly so, because they have been burned before and expect to be burned again.

But when it comes to Saturday's UFC 182 main event between Jon Jones and Daniel Cormier, they can rest assured that the hatred is 100 percent real.

This should be obvious to anyone who saw Jones and Cormier's faceoff devolve into a wild brawl in the lobby of the MGM Grand last summer. That moment created a sense of anticipation that arrives whenever Jones and Cormier are scheduled to face off again.

Jon Jones is the greatest mixed martial arts fighter in the history of the sport. A combination of carefully honed skill and innate physical tools, he's run roughshod over one of the UFC's glamour divisions.

Besides a struggle with Alexander Gustafsson in a fight he eventually won, there's been no sign that Jones will relinquish his title any time soon. In fact, if anything, it's been too easy for the young prodigy. After seven successful defenses, Jones, and the audience, have seemingly grown a little comfortable. 

Olympian Daniel Cormier, however, is the kind of man to knock you right out of your comfort zone.

When Jones enters the cage to defend his UFC light heavyweight belt, it will be more than just a typical title fight. Cormier has the physical gifts and specific skill set to give Jones a real test, to push the young champion just as he comes into his physical prime.
