Lesnar looking for revenge at UFC 100

LAS VEGAS The term passive-aggressive isnt one that you would normally associate with the sport of mixed martial arts.

However, its difficult to come up with a better one to describe the attitudes Brock Lesnar and Frank Mir have towards one another as they approach their title unification bout at UFC 100 Saturday at the Mandalay Bay Events Center.

The two have exchanged harsh words through the media, leaving one to think theres a strong hatred between the two. Instead, both fighters say its merely business.

I dont dislike Frank in any way other than hes got a win over meand I dont like to lose, Lesnar said. Revenge is a key factor here for me.

The Lesnar-Mir rematch is the co-main event for what should be UFCs biggest spectacle to date.

Canadian Georges St-Pierre, the reigning UFC welterweight champion, faces off against Brazilian Thiago Alves in the other main event while American Dan Henderson and Michael Bisping of England, the two coaches in season nine of The Ultimate Fighter, will face off in a middleweight bout that should lead to a shot at the title. T.J. Grant, the only other Canadian on the card, will fight Korean Dong Hyun Kim.

But much of the talk around UFC 100 has been focused on whether Lesnar will be able to avenge the only blemish on his MMA record, which stands at 4-1.

In his octagon debut at UFC 81, the current UFC heavyweight champion fell victim to a kneebar courtesy of Mir. Though he lost, Lesnar provided the majority of the offense during the bout.

During the first meeting between the two, referee Steve Mazzagatti stopped the action, stood the fighters up and deducted a point from Lesnar for strikes to the back of the head. Lesnar complained he received no warning from Mazzagatti and has since called the stand-up a gift to Mir.

Mir stands firm that Lesnar made a mistake by leaving his leg sticking out, and he was simply smart enough to capitalize on it.

The current interim UFC heavyweight champion also took the opportunity to launch his own verbal attack, saying he was a true martial artist while Lesnar is a fighter who only cares about big pay days.

Lesnar simply shrugged off Mirs comments.

Hes got his desires to fight and Ive got mine, Lesnar said. I truly love what Im doing, it just so happens that I get paid a lot more money than he does. Im happy the way Im doing it and hopefully hes happy the way hes doing it.

I want to live comfortably when this is all said and done. You put your body and mind through so much. I can honestly say I wouldnt fight for peanuts. Thats just who I am; Ive been there -- blood, sweat and tears for 18 years. I spent a lot of time in the gym and got paid zilch.

This is prize fighting for me. You look at it any other way and should just go fight in the underground or bare-knuckle on the streets as far as Im concerned.

Lesnar says he fights to make a living and is not out to win any popularity contests.

I dont go around looking for any respect, he added. I guess the main thing is I enjoy what Im doing. Ive got the best job in the world. I think its great I get paid to train, I get paid to fight. Im home with my family every night.

No, I dont give a damn what anybody thinks. The only thing that matters to me is Im happy and my familys happy.
