Some have complained that his level of competition hasn't been the best. Others have said his lack of English has kept him from achieving the top spot.
"Anderson Silva is the best fighter on the planet, and has been for a very long time," said Rogan, in a recent interview with USA Today. "He is a bad, bad dude. The guys on his record - Rich Franklin, Dan Henderson, Forrest Griffin, Vitor Belfort - are a murderers' row of the best fighters in the world, and not one of them even got out of the second round with this guy."
"He cemented his legacy as the best fighter in UFC history a long time ago," Rogan said.
