With 2011 coming to a close, the UFC is undergoing an unprecedented amount of change going into the new year.
With the addition of the brand-new flyweight division and a monster deal with FOX set to start on the first of the year, 2012 is set to be the biggest year in the promotion's history.
But as changes seemed to overwhelm even the most in-tune fans this year, we were also treated to some epic rematches that brought us back to as far as five years ago in some cases, and these fights ended up headlining quite a few cards in 2011.
Battles between Frankie Edgar and Gray Maynard are considered a couple of the best of the year, as was a UFC 132 title fight between Urijah Faber and Dominick Cruz.
In other cases fighters ended up avenging previous losses or disparaging performances, as evidenced by huge fights like Rashad Evans vs. Tito Ortiz, Anderson Silva vs. Yushin Okami and Forrest Griffin vs. Shogun Rua.
Some of the best and most anticipated fights of 2011 were rematches, and if the UFC is smart, which it has proven it is, 2012 should be ripe with rematches as well.
