There are a number of reasons why fans don't care to see Ortiz and Griffin match up again. Both men are getting up there in age and both are about done in the fight game. Ortiz was granted a parting wish from the UFC, as it's expected he will call it a career following the rubber match with Griffin.
Ortiz's gift may be every UFC fan's nightmare on July 7. Although the previous two encounters have been close fights to call, this battle means little for either man's career or place in the rankings.
The above mentioned qualities can be found in almost every one of the rematches on this list. Most mean very little in the broad spectrum of MMA, and nearly all of them would mean little for the two men competing as well.
Yet these fights are very real possibilities which could make MMA fans moan and groan in displeasure should they become a reality.
