At 38, Melvin Manhoef (29-13-1) is a finished product. You know exactly what to expect when he fights. There will be violence. It will be furious. And someone will end up looking at the ceiling.

Fifty-four times, in a career spanning almost 20 years, it's been his opponent who has been unable to finish the fight—the victim of powerful winging punches that are truly frightening to behold.

"I'm a junkie for the knockout," he said on the Bellator 133 broadcast, moments before walking to the cage. That's not subtle—but it's self-evidently true.

In recent years, as he's slowed and grapplers have improved their games, he's been the victim of his own success, chasing glory too often for his own good. When Manhoef smells blood, all science fades. There is only violence.

No matter what happens when Benson Henderson takes on Brandon Thatch in the main event of UFC Fight Night 60 on Saturday, we’re probably going to need an asterisk or two.

Henderson vs. Thatch isn’t a fight that figures into anyone’s long-term plans, nor one we even could’ve anticipated as recently as a month ago. Make no mistake, there are clear stakes here for each guy, as Bendo moves up from lightweight to make a short-notice appearance at 170 pounds.

It’s just that putting it all in perspective will likely take some footnotes.

Obviously, this wasn’t the original blueprint. When UFC brass first marked it up on the whiteboard at Zuffa LLC headquarters, a stunningly relevant 170-pound contender bout between Matt Brown and Tarec Saffiedine* was meant to headline the Valentine's Day spectacular in Broomfield, Colorado.

On Tuesday evening, the mixed martial arts Internet exploded with the news that Frankie Edgar and Urijah Faber would potentially, possibly, probably headline the UFC's first foray into the Philippines.

On Wednesday, the promotion made it official (via Thomas Gerbasi of UFC.com): The former UFC lightweight champ and the former WEC featherweight champ will do the five-round thing (at 145 pounds) against each other on May 16 in Manila.

But even before the fight was made official, the debate began raging (because MMA fans love nothing more than a debate): Should Edgar vs. Faber be considered a superfight? Arguments were made. People were right. The other people they were arguing with were wrong. On the Internet, there is no gray area: You're either correct, or you are an idiot.

Today, Jonathan Snowden and Jeremy Botter—MMA's version of Batman and Robin—get back together for another episode of "The Question." This time, they discuss whether Edgar vs. Faber can truly be considered a superfight.

Over the past seven days, I have gone in hard on the UFC and its drug testing issues. I've said I believe they have a problem with performance enhancing drugs. I expressed my disappointment in their decision to cancel a planned comprehensive testing program that would randomly test every fighter on the UFC roster.

And I spoke of my belief that, if things did not change, it could lead the UFC and mixed martial arts in the wrong direction.

Today, we got our first glimpse that change might be on the horizon and that the UFC understands that changes must be made.

During Wednesday's broadcast of UFC Tonight, the hosts—Karyn Bryant, Daniel Cormier, Michael Bisping and guest Demetrious Johnson—discussed the issues surrounding PEDs in the UFC. The program noted that 13 UFC fighters have failed drug tests in the last 12 months. It was a moment of brutal honesty from a UFC-controlled show that could have easily avoided the subject altogether.

Maybe we’re all feeling a little bit like Alexander Gustafsson right now.

You remember how Gustafsson’s 2015 started, right? The erstwhile light heavyweight No. 1 contender rolled into a Jan. 24 title eliminator against underdog Anthony Johnson with sky-high expectations, only to get flattened—crushed, really—in two minutes, 15 seconds.

Gustafsson left the Octagon in tears in front of roughly 30,000 fans in his hometown of Stockholm, Sweden. He was probably still a little dazed, wondering how a thing that was supposed to be so great so quickly went so wrong.

Yep, that’s us.

Already reeling from a raft of recent bad news, Tuesday found us neck-deep with yet another positive drug test. This time it was Hector Lombard, pulled from a scheduled bout with Rory MacDonald at UFC 186 after some unpronounceable steroid turned up in his system.

If more fighters took the same kind of public stance on performance-enhancing drugs as UFC middleweight Tim Kennedy, the sport of mixed martial arts might be better off.

Not everybody can be Kennedy, of course. He is nearly one of a kind: a cerebral and talented fighter who is willing to speak his mind. He is a special forces operator who still, 12 years after beginning his professional mixed martial arts career, still does sporadic "work" for the United States government. What kind of work, Kennedy won't say. But it is safe to assume that, given his background as an elite sniper, Kennedy isn't building roads in foreign countries.

But more importantly to our interests, Kennedy is unafraid and unapologetic when it comes to the subject of PEDs. He believes mixed martial arts is a dirty and broken sport, and he is so disillusioned with the way things are going that he's not sure he'll ever fight again. He is not retired, he told Ariel Helwani on Monday's edition of The MMA Hour (h/t MMA Fighting). But he also is not in a hurry to get back in the Octagon.

Kennedy isn't scared of pointing a little blame at Lorenzo Fertitta and Dana White, either. He told Helwani that he sees what he believes is "lip service" from White and Fertitta every time somebody fails a drug test. Changes are promised, Kennedy said, "and then nothing changes."

LAS VEGAS — Daniel Cormier stood backstage, moments away from making the most important walk of his athletic career.

He'd trained for this moment since the day his local high school wrestling coach pulled him off the street and tossed him into a wrestling room, where his life would change forever. Through all of the heartbreak, through the failed attempts at winning Olympic gold, Cormier had just one thing on his mind: being the best in the world.

He had never reached his goal in wrestling. He was famously forced to pull out of the Olympics in 2008 after a weight cut gone bad. But finally, he had his chance.

It is perhaps a fighter cliche, but Cormier had trained harder than ever. He was ready. And he believed in himself and in his skills.

You aren’t going to like this.

The price of expunging performance-enhancing drugs from mixed martial arts will be steep, and fans will need to shoulder at least some of the cost.

Sorry, I know that stinks to hear. At this point, though, we all owe it to each other to start telling the difficult truth. In the wake of last week’s revelation that former middleweight champion Anderson Silva failed a pre-fight drug test for his UFC 183 bout against Nick Diaz, drastic action is necessary.

No one can say for sure if there is a PEDs epidemic going on in MMA, but it’s sure starting to seem that way. Silva’s positive test felt like a tipping point of sorts. If the consensus greatest fighter of all time is on steroids, it’s pretty easy to imagine the rest of the sport might have a fairly widespread problem.

The Ultimate Fighting Championship has a drug problem.

If you weren't already aware of this, you are now. 2015 started off with a bang for the promotion, with two consecutive pay-per-view events headlined by appealing fights.

Jon Jones vs. Daniel Cormier? Sign me up for that one.

The return of both Anderson Silva and Nick Diaz, and they're facing each other? Are you kidding me? I am thankful I was able to see both of those fights in person.

In a video released Thursday, veteran Ultimate Fighting Championship middleweight Michael Bisping said the news of Anderson Silva's test failure for performance-enhancing drugs has tarnished his entire legacy.

Silva, 39, failed a random January 9 test for the substances drostanolone and androsterone. The promotion announced the news Tuesday evening. In a statement from Silva's manager, Ed Soares, provided to Damon Martin of FoxSports.com, the fighter proclaimed his innocence and said he will contest the failure. It was the first positive test of Silva's career.

But Bisping said Silva being nabbed on his first out-of-competition test could lead him to believe the former middleweight champion has been using PEDs for the entirety of his career.

"My initial reaction was sadness, disappointment. I was disappointed in Anderson, but then I thought about it and was like, 'Hold on a minute—this doesn't surprise me at all,'" Bisping said. "I believe this was the first time he was tested out of competition. So who's to say that he hasn't been doing this his entire career? That's the question that is always going to be asked.
