Brock Lesnar's loss to Cain Velasquez could end up being a blessing in disguise for Dana White's blossoming empire.
The biggest draw on the ticket ended up being the biggest loser of the night.
Instead of watching the bigger Lesnar steamroll Cain, UFC fans were treated to a ferocious display of technical MMA artistry.
Lesnar left the Octagon bloodied and battered, with possible designs on returning to WWE in a more civil match against the Undertaker.
Meanwhile, Cain will stand above all in the MMA world.
Here's a look at why Brock Lesnar's loss to Cain Velasquez is good for MMA.
Lesnar's growing fame helped make UFC 121 big news around the sports world in the days leading up to the fight.
Millions tuned into the pay-per-view fight and were treated to plenty of violent action.
In the end, Cain's win could lead to even more opportunities for Dana White to market UFC in the coming months and years.
There's nothing worse than getting hyped up for an exciting sporting event, only to be sorely disappointed.
That wasn't the case Saturday, when Lesnar and Cain met in the Octagon.
Lesnar attacked from the start, taking down Cain and looking to dominate with his superior size.
But Cain's MMA talents got the better of Lesnar, who was soon staggering after taking a knee to the sternum and repeated shots to the face.
It certainly made for great theater.
Saturday's fight provided a dose of unabashed, authentic testosterone.
Lesnar and Cain managed to keep the fight itself bigger than themselves. When it was over, both men showed respect for each other.
MMA certainly has plenty of substance behind the style.
It's hard to believe it, but MMA and UFC are far from done growing.
With the steady decline of boxing thanks in part to the bizarre Pacquiao-Mayweather standoff, Dana White has already lifted UFC to considerable heights.
His next step is to continue to market his product globally.
White has never had a heavyweight with a great deal of marketing power, but that should change with Cain's Mexican heritage.
Who says UFC needs Lesnar as a marketing chip?
Lesnar's background as a wrestler suggests he might have any easier time finding success in the ring.
After taking a pummeling at the hands of Cain, he walked by the Undertaker in what was likely a staged interaction.
The Undertaker issued a challenge to Lesnar, saying "Wanna do it?"
After the exchange, rumors began to swirl regarding a possible meeting between Undertaker and Lesnar in April 2011.
Don't be surprised if he agrees to return to WWE, at least for one match.
It remains to be seen if Lesnar is truly committed to improving his MMA skills.
Lesnar's background as a wrestler--both amateur and professional--may have actually made his transformation to MMA a bit more challenging.
Cain also had success as an amateur wrestler, but began his MMA career immediately after finishing college.
Lesnar's ability to grapple for position is of less importance than his ability to strike, something Cain clearly excelled in Saturday night.
Although wrestling provides potential MMA competitors with good background, the technical skills required to succeed in the Octagon have escaped many who have tried.
For the moment, it appears Lesnar has a long way to go before becoming a complete fighter.
Despite a perfect record in UFC competition, the 28-year old Cain Velasquez entered Saturday's fight as an underdog.
He left as a household name.
Now, with a 9-0 lifetime record, the soft-spoken heavyweight champ will have no problem getting credit for being a great fighter.
An outsider isn't just going to walk right in and steal the spotlight inside the Octagon.
It's not always fun for the favorite to win without the opponent putting up much of a fight.
With the underdog Cain triumphing, fans were put on alert that the competitive balance in MMA is alive and well.
Cain has been around for a long time, but he has never enjoyed nearly the acclaim that he will in the weeks and months ahead.
Just like reigning UFC middleweight champ Anderson Silva, Cain should create numerous marketing opportunities for MMA on a global scale.
With his clean personal life and his ability to broaden MMA's popularity across the United States' southern border, there is no doubt that Dana White should be excited about what the future has in store.
Cain might have won Round 1 against Lesnar, but could he also win a Round 2?
There is nothing better than watching a fallen favorite try to rebound from a bitter defeat.
That could happen at some point if Lesnar and Cain were to meet again in the Octagon.
A rematch likely would produce historic pay-per-view ratings and a massive financial windfall for White and the UFC.
The drama is already beginning to build...
