It seems rematches have become more and more common in MMA.
Why?
Because rivalries sell in combat sports. Had it not been for the bad blood between Ronda Rousey and Miesha Tate, women's MMA probably wouldn't be where it is today. A recent grudge between Anderson Silva and Chael Sonnen also helped MMA skyrocket in popularity in Brazil.
More than animosity is needed to make a great rivalry, though. If an unproven prospect starts throwing verbal jabs at Jon Jones, that alone isn't going to get them a shot at the light heavyweight champion.
