Chances are pretty good that Sarah Kaufman is not going to be a crossover superstar. She'll probably never be invited to walk the red carpet.

Kaufman is one of the finest mixed martial arts fighters, a former Strikeforce bantamweight champion, and one of the nicest people you'll ever meet. Consider yourself lucky if Kaufman counts you among her circle of friends.

She's been obscured, though, in the near total eclipse that Ronda Rousey casts upon the rest of women's mixed martial arts.

Rousey is the sport's "it girl." She was on the cover of ESPN the Magazine's body issue. Dana White wore a t-shirt with a picture of the cover on it to a recent UFC weigh-in.

Kaufman said she's met White a couple of times and is pretty sure the UFC president knows who she is.

Rousey's star power, though, hardly offends Kaufman. Just the opposite; Kaufman enjoys it because it provides her a platform for her to

Mythic tales of super human feats rise out of boxing gyms around the world. If you want to hear a story about the greatest fight you never saw or the most vicious knockout that never occurred, talk to the folks who hang around gyms and you'll be regaled by stories that have seeds of truth but have been nicely embellished.

And then there are the tales of Randall Bailey, this soft-spoken lithe boxer from Miami who isn't the sort to call attention to himself.

But marveling about Randall Bailey's punching power has become as passé in his camp as getting excited that a light turns on when a switch is flipped.

It's an everyday occurrence that he does something that would awe a visitor to his camp.

One of his trainers, Chico Rivas, a boxing lifer from Florida, said he's seen so much in his seven years with Bailey that it would take far too long to recount them.

His promoter, the

Ranking fighters is a difficult proposition under perfect circumstances. Doing it in situations like the one involving Frankie Edgar increases the degree of difficulty a hundredfold.

Edgar is clearly one of the elite fighters in the world. He's proven that repeatedly, in wins over lightweight stars such as B.J. Penn, Gray Maynard and Jim Miller, among others.

He's fought a very high level of opposition and has yet to be blown out in his fights.

He's 14-3-1, which in MMA qualifies as an exceptional record. But he's 1-2-1 in his last four.

Of course, the losses were razor-thin decisions to Benson Henderson in lightweight title matches. Edgar lost his title to Henderson on Feb. 25 in Japan in a fight so close it merited an immediate rematch. Henderson then took a split decision Aug. 11 at UFC 150 in the rematch, though many have been outraged at the call, believing Edgar won.

At this point, the question becomes how to deal with Edgar in the rankings given the stark reality of

DENVER – There were a lot of dour faces on the dais Saturday at the UFC 150 post-fight news conference in the bowels of the Pepsi Center, about an hour after Benson Henderson won a hotly disputed split decision over Frankie Edgar to retain his lightweight title in the show's main event.

For the second week in a row, the UFC put on an outstanding show. If last week's card in Los Angeles was an A-plus, Saturday's card would probably grade out as an A-minus, highlighted by Donald Cerrone's hellacious knockout of former teammate Melvin Guillard in the co-main event.

The somber moods were clearly the result of how the main event was judged. Though the Henderson-Edgar fight lived up to its billing as a quality match, few were happy with the split decision outcome.

UFC president Dana White refused to give his score, saying only that he had it 2-2 after four rounds. Most media scored the fight for Edgar. Fans on social media favored Edgar, though by a lesser margin than the

DENVER – Benson Henderson and Frankie Edgar battled almost to a standstill Saturday in their lightweight title fight in the main event of UFC 150.

Henderson pulled out a split decision, winning 48-47 on two cards and losing 49-46 on the third to retain the title he won from Edgar at UFC 144 in Japan.

Edgar was elusive and difficult for Henderson to catch. Henderson, who had an 89-62 edge in strikes landed, was scoring well with kicks early in the fight. But as the bout wore on, Edgar was more in control.

The decision is sure to spark plenty of debate. It drew the ire of the crowd at the Pepsi Center on Saturday, and Edgar won 49-46 on the Yahoo! Sports card.

Henderson celebrated when the fight end, but admitted he wasn't sure when it was announced that he'd kept his belt.

"Of course, you always have concern when it goes to the judges," Henderson said.

His biggest concern was in the second after Edgar caught him in a choke. But Henderson has been the most difficult

The numbers that brothers Wladimir and Vitali Klitschko have compiled should say all that needs to be said: 102 wins in a combined 107 fights, with 91 of those coming by knockout. Between them, they hold every major heavyweight championship belt there is.

Those numbers, though, are a bit misleading. Imagine how LSU or Alabama would be regarded at the end of the college football season if their 12-0 marks included wins over Buffalo, Duke, UNLV, Army and Kent. There would be outrage and their position in the polls would reflect that.

There is, however, a difference: The Klitschko brothers aren't choosing to fight a weak caliber of opponents. The guys they're fighting are the best there are, by and large, in a heavyweight division that is among the weakest in history.

They're doing what they should do to the kind of opposition they are facing: They're obliterating them. Wladimir Klitschko has scored knockouts in seven of his last eight fights and has barely lost so much as a

One of the endearing images of UFC 144 came in the immediate aftermath of Benson Henderson's lightweight title-winning effort over Frankie Edgar in Tokyo.

Henderson walked down a hallway in the Saitama Super Arena, sweat dripping from his long hair, his arm draped over his mother's shoulder. Song Henderson carried her son's oversized UFC belt on her tiny shoulder, frequently looking up almost worshipfully toward her son.

Benson Henderson: "I want to fight everybody in the division."

Then, in the wake of the most significant professional achievement of his life, Henderson went on vacation in South Korea to celebrate. And, of course, he took his Mom on the trip with him.

Henderson, who makes the first defense of his title on Saturday in Denver when he rematches with Edgar in the main event of UFC 150, can't quite understand the fuss:

What kind of man doesn't dote on his mom, he seems to say.

Henderson, though, is a different kind of athlete and a different kind of fighter. He's a socially conscious young man whose Twitter stream is

Sometimes, I get the feeling that Frankie Edgar could beat Anderson Silva and Jon Jones on back-to-back nights and then be hounded on the third about a potential move to featherweight.

As one of the more entertaining fighters in the UFC, Frankie Edgar always commands a crowd.

The desire to see Edgar drop from lightweight to featherweight is perplexing because there is nothing – not one single shred of evidence – that suggests he needs to do it.

It would be fantastic to see Edgar drop down, if only temporarily, simply because a match with featherweight champion Jose Aldo would be so appealing.

The notion, though, that Edgar somehow needs to move down because he's not good enough to cut it at lightweight is almost as ludicrous as asking if the Cubs have a chance to win it all this year.

Edgar, at lightweight, is one of the great fighters in the world. He's 14-2-1, with one of his losses coming to Gray Maynard in 2008 and one of his losses coming to Benson Henderson in an excruciatingly close lightweight title fight in February. The next time he gets blown out will be
