It is fair to say that the Ultimate Fighting Championship (UFC) heavyweight division is very top-heavy, with a huge drop in talent after the number two contender spot in the current UFC rankings.

Cain Velazquez is the reigning UFC Heavyweight Champion and he will face No. 1 contender Fabricio Werdum at UFC 180, the company's first foray into Mexico as they try to break into that market. Sitting at No. 2 is the former champion, Junior Dos Santos, who has given Velazquez problems in the past, having beaten the champ at the first-ever Fox live telecast of a UFC event only to drop the title to the Mexican heavyweight champion at UFC 166.

Sitting at the third spot is Travis Browne, who lost to Werdum via decision back in April, followed by Stipe Miocic, Mark Hunt, Josh Barnett, Andrei Arlovski, Antonio "Bigfoot" Silva, Roy Nelson and Ben Rothwell.

Former UFC Heavyweight Champion Brock Lesnar, whose contract with the WWE is rumored to expire after Wrestlemania 31, has to scoff at the mention of some of those names on the UFC heavyweight rankings, having held the title despite competing in only eight mixed martial arts (MMA) fights.

People questioned whether Lesnar could compete in the UFC when he first made the move into MMA, where the blows were real (despite the physicality of professional wrestling), dismissing the fact that "The Anomaly" had accomplished amateur wrestling career -- including becoming a two-time National Junior College Athletic Association All-American (NJCAA) and a two-time NCAA All-American, as well as winning two Big Ten Conference championships, the 1998 NJCAA Heavyweight Championship and the 2000 national NCAA Heavyweight champion. The derisive jokes of "Put him in the figure-four leg-lock, Brock!" or "Do a moonsault!" from finicky MMA fans quickly ended when Lesnar beat the legendary Randy Couture in 2008 at UFC 91 in the second round via technical knockout to win the UFC Heavyweight Championship.

Lesnar left UFC in 2011, forced into retirement from MMA after losing to Alistair Overeem at UFC 141. Lesnar had been attempting to come back from surgery after having 12 inches of his colon removed to help treat his diverticulitis - which are small, bulging sacs or pouches of the inner lining of the intestine that become inflamed or infected.

"We have not seen a star like him since he left," said Ariel Helwani, host of the "MMA Hour" podcast, during an interview with Paul Heyman -- who has helped advise Lesnar throughout his MMA career as well as professional wrestling. "We never saw a star like him until he got there [to UFC]. He really helped put the UFC on the map, in my opinion. He got them pay-per-view numbers that they've never gotten since then, never had before then."

Maybe it would take Lesnar some time to acclimate if he were to return to The Octagon and age may be a factor (he is 37 years old, after all) but looking at the UFC top 10 heavyweights, Lesnar has to like his chances against many of the competitors on the list. Lesnar could certainly overpower Arlovski, who is 35 years old and has shown he has a glass chin. Hunt, who recently handed Nelson, 38, his first knockout loss in his career, is 40-years-old. "Bigfoot" Silva is 35 years old, Barnett is 36, and Miocic is 35.

Even the upper-echlon fighters like Dos Santos, 30, Werdum, 37, and Velazquez, 32, are all in their 30s. Given all that, age is should not be a negative factor for Lesnar if he wanted to return to the sport MMA.

With his WWE contract possibly expiring early next year, Lesnar may be open to listening to any UFC offer, either to use them as leverage in a negotiation with the WWE or to end his MMA career on a higher note than he did against Overeem.

Lesnar almost made that jump in 2012, when he was offered a mega-fight against the legendary Fedor Emelianenko at AT&T Stadium in Dallas, TX.

"Ready, willing, able, and already starting up pre-training camp," is how Heyman described those negotiations to Helwani before a deal could be made with the UFC and the the Russian-born fighter.

"Fedor's father passed away and Fedor lost all desire and motivation to fight," said Heyman as to the reason why the dream mega-fight never occurred.

UFC President Dana White is no fool when it comes to making money and knowing full well that four of the company's top ten highest earning PPVs, as far as buyrates, featured Lesner (UFC 100: Lesner-Frank Mir, UFC 116: Lesnar-Shane Carwin, UFC 121: Lesnar-Velasquez and UFC 91: Lesnar-Couture), he may make an offer that would be difficult for Lesnar to turn down.

But for the time being, Lesnar is going nowhere and focusing on his sports entertainment career with the WWE and not a return to the UFC.

"I think [Lesnar] is very, very, very, happy right now with what we are doing in WWE," said Heyman to Helwani during the August interview. "So it's just not a subject right now he has to think about. If the deal ends up over with the WWE, if a change in circumstances happens to where it's a no-brainer to get Brock back into the cage perhaps it's something that he would consider. But at this moment, it's not a topic of conversation because things are going so will with WWE why would you mess up the perfect deal."
