The UFC 137 main event has gone through a whirlwind of changes since the original fight between Georges St-Pierre and Nick Diaz was announced earlier this year. After some miscommunication and hard-headedness from Diaz, the former Strikeforce champion was then replaced by Carlos Condit. This moved knocked Diaz down to the semi-main event against B.J. Penn.
Things got even crazier recently when GSP had to drop out of the main event due to an injury, leaving Condit with the tough decision to drop out of the event himself to guarantee his eventual title shot and not create controversy if he were to lose a fight.
With St-Pierre vs. Condit now off, Diaz vs. Penn takes over as the main event of what was expected to be one of the bigger pay-per-view events of the year. Though some fans are unhappy about how things have turned out, the truth is that UFC 137 is still a very stacked card and the Diaz-Penn fight might actually be more entertaining than the original GSP-Condit fight.
The anticipation for Diaz-Penn continues to grow, and here are five reasons why we cannot wait for the UFC 137 main event!
