With one of the most impressive resumes in the history of mixed martial arts, BJ Penn is undoubtably one of the greatest fighters of all time. The UFC Hall of Famer, who is one of only two men to hold UFC championships in two weight classes, is still widely regarded as one of the top pound for pound fighters on the planet.

During a recent interview with TMZ, UFC President Dana White explained that Penn could have been even better, and done even more in the UFC, to cement his place as the greatest of all time.
