BJ Penn is also another LW that has been underrated on here based on his last few fights. People were fans of BJ because of his willingness to scrap with the best in the world. He put on a tournament in Hawaii called Rumble on the Rock just so he could fight Gomi who was ranked #1 at LW in 2003. After he beat Gomi, he went up to challenge Hughes at WW when Hughes was widely considered the WW GOAT and strangled him for the belt. Then he goes to K1 to fight Machida at HW and loses a UD. Outside of Saku and few others, there weren't many fighters back then that were willing to take on challenges like BJ and there certainly aren't any now.
