Perhaps best of all for White and company, Lesnar will continue to work hard to improve. When you ask Lesnar’s trainer Greg Nelson about what impressed him from the first seconds he worked with the current champ, he cites Lesnar's work ethic above all else.

“Definitely he’s a great athlete, but his ability to want to learn? That’s a huge thing,” he said.

A dominant champion would be an answer to the UFC’s prayers. Everyone loves a dominant champion. Everyone’s intrigued by a dynasty. It’s why Mike Tyson captured the national consciousness, why the Dallas Cowboys are “America’s Team” and why the New York Yankees are still the financial kings of baseball.

LeBron may not have a title but everyone understands his impact on the game. He makes the casual audience take notice and brings in new fans. Lesnar can have that same effect for the world of MMA, ushering in a new era. On Saturday and Sunday, the UFC saw more media and fan attention than it ever has in its 15-year existence, and that is in many ways attributable to the new champ.

This is the kind of impact Lesnar has: Famed British boxer Ricky Hatton was in the crowd on Saturday night, and upon being asked about him, Hatton said: "Brock's a big bloke, isn't he? If you found him in bed with your girlfriend, you'd tuck him in!"

That's superstar presence.

There are challenges ahead for Lesnar in the future, of course. Next month, Antonio Rodrigo Nogueira and Frank Mir will square off for the right to face him. Both fighters excel in the jiu-jitsu discipline that will offer Lesnar his biggest technical problem (in fact, Mir beat him in his UFC debut back in February).

In the distance, there are unbeatens Cain Velasquez and Shane Carwin, both of whom – like Lesnar – have distinguished amateur wrestling backgrounds. Junior Dos Santos, who trains with Nogueira, is looked at as a threat, and Gonzaga still holds promise.

Lesnar has plenty of tests in front of him, plenty of opportunities to prove that he is not a former pro wrestler who won the title, but a phenom who found his calling a little later than most.
