5 times it backfired badly when UFC fighters disrespected their opponents

#4 Frank Mir vs. Brock Lesnar

Lesnar got his revenge on Mir

After Frank Mir defeated Brock Lesnar in the Beast's first UFC fight, many people thought that Brock didn't belong inside of the octagon - including Frank Mir. However, Lesnar would go on to win the UFC Heavyweight Championship and defend it against Mir himself in a rematch at UFC 100, which, to this day, is one of the biggest events in the company’s history.

Mir verbally destroyed Lesnar during the build-up, stating that he didn't even remotely deserve to hold the title and that the UFC essentially handed him the championship. Of course, Lesnar didn't take too kindly to this, battering Mir in the second round of the main event to ensure that he would be forever known as the undisputed Heavyweight Champion of the world. Not a bad way to make a statement.

We conclude with a victory that was a little more calculated.
