UFC 112 on Saturday will be a rare opportunity to see two of the five best pound-for-pound fighters in mixed martial arts on the same card, but it will be more than just that. It will also be an opportunity for both UFC middleweight champion Anderson Silva and UFC lightweight champion B.J. Penn to make a case for being not just top five, but the best fighter in the world.
Right now, I consider Silva the sport’s second-best fighter and Penn the fourth. But they Top 4 fighters are bunched together so tightly that with No. 1 Fedor Emelianenko dragging his feet in scheduling his next fight, a spectacular performance from Silva or Penn could convince me to make a change at the top.
My rankings of the top 10 pound-for-pound fighters heading into UFC 112 are below.
