MMA's 10 best pound-for-pound fighters

First it was Urijah Faber who was supposed to lord over the featherweight division. Then it was Mike Thomas Brown. Now Jose Aldo has run roughshod over both of them, and he appears to be in position to reign with impunity at 145 pounds.

With a brutally dominant showing at WEC 48 in Sacramento, Aldo took out the sport's most recognizable featherweight on the promotion's biggest card to date. To be sure, there were many new fans who thought they were tuning in to another UFC card Saturday, only to see Aldo batter Faber in thoroughly impressive fashion.

Meanwhile, WEC 48 also marked the emergence of the man who will likely be Aldo's next challenger, Manny Gamburyan. The coming-out party for the powerful Armenian came at the expense of former featherweight champion Brown. Less than halfway into the first round of their April 24 encounter, "The Anvil" landed a short right hook that put Brown on the deck. Gamburyan then swarmed to finish, earning himself a likely crack at Aldo and erasing Brown's entry on this list.
