Ranking mixed martial artists is, to be fair, an inexact science. Rules across the sport are dissimilar, weight classes don't always conform and fighters have been known to jump from division to division. And all such factors played into SI.com's latest MMA rankings.
Though there was little movement from heavyweight through lightweight in comparison to last month's list, featherweight and bantamweight registered several notable changes.
With the start of Sengoku's featherweight tournament this Friday in Japan, WEC 40's bantamweight-heavy lineup coming April 5, and Bellator Fighting Championship's debut next month, don't expect the 145- or 135-pound divisions to remain stable, save for the top, where Mike Thomas Brown and Miguel Torres firmly hold the No. 1 spot in their respective classes.
Some notable updates:
• Nate Marquardt moves up a couple spots at 185 after soundly defeating Wilson Gouveia.
• Undefeated Paulo Thiago debuts at welterweight at No. 7, thanks to his KO of previously top-five ranked Josh Koscheck.
• Nick Thompson revolves back in at 170, replacing Matt Serra, whose win over Georges St. Pierre feels long forgotten.
• Gray Maynard moves up one spot at lightweight, as he continued an increasingly impressive run with a dominant decision over Jim Miller.
And so, without further ado, here is the latest mix-up in SI.com's MMA rankings.
