ScorecardMMA

Junior dos Santos has the biggest jump in last 2 years. He was ranked 111 in HW division 2 years ago and now he is #4. His Current Score almost tripled (from 255 to 660). This gives him an incredible Progress coefficient of 180.
Bibiano Fernandes is now Dream Featherweight Champion and 2 years ago he was fighting in obscure Raw Combat organization.
Largest jump in ranking goes to Chad Mendes who was just starting to fight 2 years ago and he is now #13 in 145 Category. In 2 years he went from #351 to #13.

Unfortunately, we have to declare that biggest drop in last 2 years goes to Jens Pulver. He lost 211 points and went from #2 to #43 in FW division.
It is interesting that Paulo Filho is also a big loser, even with a positive Win/Loss. This is because he is fighting much inferior opponents then before.

Largest jump in last couple of weeks goes to Narantungalag. He was a little known fighter who has now a win against Akihiro Gono.
With his first loss Big Mo has significant drop in ranking.

Since Zuffa (UFC & WEC) is dominant in all weight categories, let's see who are the Top Fighters outside of Zuffa:
