UFC 137's Facebook prelims sport a pair of middleweight contests but not one ranked fighter between them.
UFC 138 is being headlined by #4 Mark Munoz and #13 Chris Leben, but is otherwise devoid of middleweight action.
UFC 139 gives us one of the more interesting middleweight match ups in #18 Wanderlei Silva vs. Cung Le as well as #21 Chris Weidman vs. Tom Lawlor.
Based on the premise that all MMA rankings are subjective but that it’s still useful and informative to know who the online MMA community as a whole ranks as the best fighters in MMA, we collect and average the rankings of the top MMA websites to produce our consensus rankings. We compile the top MMA rankings from each of our sources and award 25 points for a first place ranking, 16 for a 10th place ranking, 1 for a 25th place ranking. A formula is used to "normalize" the data so all fighters are awarded points from those lists that do not include a full 25 fighters. This formula ensures that each ranking site awards the same number of total points regardless of how many fighters they choose to rank. Each fighter’s total is divided by the number of possible points to determine their standing in the Consensus Rankings.
