Mir's father convinced him to begin wrestling in high school after seeing how easily strikers were taken down in the initial UFC tournaments. Though Mir lost his first seven wrestling matches, he did eventually win a state championship in the sport in 1998. Upon graduation, he began training in Brazilian Jiu Jitsu and received his black belt in it from Ricardo Pires in 2004.
His victory over Williams announced to the world that the former Kenpo practitioner was now one of the world's most dangerous submission fighters.
Mir fell by way of first round TKO after clearly fatiguing rather quickly. His performance caused many to wonder about his cardio and drive to succeed. Regardless, Mir picked up his winning ways after the Freeman encounter rather quickly.
With the win, Frank Mir became the UFC Heavyweight Champion.
On September 17, 2004, Mir was knocked off his motorcycle by a car, causing both a break in his femur and the tearing of all the ligaments in his knee. When Mir was unable to defend his title a year later, the UFC offered Arlovski his heavyweight championship.
But then came three straight victories against Antoni Hardonk, Brock Lesnar, and UFC Interim Heavyweight Champion Antonio Rodrigo Nogueira (giving him Nogueira's old title).
Frank Mir was clearly back.
In other words, most MMA fighters know that once you get caught by Mir it's all over. He's just too strong to power out of his attempts and too good to use technique to escape.
Some of Frank Mir's Greatest UFC Wins
- Frank Mir defeats Antonio Rodrigo Nogueira by TKO at UFC 92: Mir and Nogueira had opposed each other as TUF 8 coaches prior to this interim title bout. Though Nogueira had been the favorite coming in, Mir dominated from beginning to end, especially in the way that he showed off his improved striking skills. It was the first time that Nogueira had been stopped in his career.
- Frank Mir defeats Brock Lesnar by kneebar at UFC 81: If Brock Lesnar were to defeat a former UFC heavyweight champion in only his second match, the uneducated might have assumed that MMA fighters weren't any better at fighting than professional wrestlers (forget that Lesnar was a former collegiate wrestling champion, as it wouldn't have been what the masses focused on). Regardless, Mir took advantage of a mistake by his bruising opponent on the canvas and turned it into a kneebar victory.
- Frank Mir defeats Tim Sylvia at UFC 48 by armbar: Let's put it this way: Tim Sylvia didn't tap when Mir caught him in a first round armbar. That led to his arm breaking on national television and the situation being replayed over and over and over again for people to see.
- Frank Mir defeats Pete Williams by shoulder lock at UFC 36: When Mir defeated Williams by a vicious shoulder lock, the world was introduced to one of the scariest heavyweight submission fighters ever.
