9. Paulo Filho
Filho was for a time in the best-middleweight-in-the-world discussion, and it seemed inevitable that the Brazilian would eventually make his way to the UFC. He was 11-0 when he entered the 2006 Pride welterweight grand prix and quickly rattled off three wins, two of them via armbar submission, to reach the tournament final. However, an injury left Filho unable to compete.
When the WEC merged into the UFC, Filho became a free agent. Though he won his next four bouts, the Brazilian grappler was never the same. Filho has not fought since February 2014, when he lost a unanimous decision to Andre Muniz under the Bitetti Combat banner. His resume includes victories over Murilo Rua (twice), Melvin Manhoef, Ryo Chonan and Kazuo Misaki.
