We all love a good rivalry.
It's nice to see two dudes who respect each other enter the cage to see who's better, but when they talk trash for a month and shove each other at the weigh-in, it always adds a little something extra.
Look at Ronda Rousey and Miesha Tate. The two were set to square off in Strikeforce early in 2012 and were absolutely seething at one another by the time they did. Rousey thought Tate was an easy target, Tate thought Rousey was a disrespectful nobody.
Since then, Tate's arm ended up bending the wrong way at the elbow, women ended up in the UFC, the two were rival coaches on TUF, and they both stand to get very, very rich together at next month's UFC 168.
Let's take a look at some other rivalries presently going on in the UFC.
