In almost all of our divisional rankings there is a clear #1, but not always a clear #2 or #3. Consider these matches and give us your thoughts on how they will/would go down.
.
Heavyweight (#2)
#2 
Frank Mir vs. #3 Brock Lesnar
The sequel, which is already scheduled to happen. The winner of this should become a clear #2 at Heavyweight, not only in our ratings, but in the minds of MMA fans.
.
Light Heavyweight (#1)
#1 Rashad Evans vs. #2 Quinton Jackson
Although Machida/Evans should do a good job in determining a clear #1, Jackson/Evans is the optimal match-up.
.
Middleweight (#2)
#2 
Demian Maia vs. #3 Jorge Santiago
The undefeated Maia against Santiago, who is on a torrid run. Two brazilians facing off to see who gets the next shot at their fellow countrymen. Will probably never happen.
.
Welterweight (#3)
#3 Jon Fitch vs. #4 Jake Shields
UFC’s perennial contender versus a Bully Beatdown alumni.
.
Lightweight (#1 or #2)
Satoru Kitaoka, B.J. Penn, Kenny Florian
Lightweight is a mess. We’ll get Penn/Florian later, but Kitaoka is at the top of our rankings right now. Any matchups between these three would bring some clarity to the division.
.
Featherweight (#3)
#3 Wagnney Fabiano vs. #4 Yuji Hoshino
With a pretty clear #1 and #2, a Fabiano/Hoshino victor would become at least #3, and possibly pass Faber for the #2 spot.
.
Bantamweight (#2)
#2 Rani Yahya vs. #3 Brian Bowles
Brian Bowles is in line to get the next title shot, but the FightMatrix computer believes he has been passed up by Yahya. Since losing to former top WEC Bantamweight Beebe, and the elite Yamamoto, Yahya has submitted two Top Bantamweights in the first round.
.
Flyweight (#2)
#2 Yuki Shoujou vs. #3 Ryuichi Miki
Yamaguchi and Urushitani have been pushed to the side by up-and-comers Shoujou and Miki. Shoujou lost to Yamaguchi, beat Urushitani, then lost in his title shot to Kojima. Miki has not lost in over three years, but does not have a win against a top Flyweight opponent.
.
Women (#1)
#1 Megumi Fujii vs. #2 Tara Larosa
Due to a lack of quality opposition, former #1 LaRosa has been passed by Fujii. They are about 20 pounds apart, but we can dream about a catchweight bout between them. Tsuji/Fujii may be more likely, and the winner of that would come out as a clear #1.
