BJ Penn is a legend for a lot of reasons. One of the first guys who was sick at jujitsu but would also box your face off. He won the mundials at black belt level after I believe only 3 years of training. Then he beats Heughs, arguably beat GSP, became Champ at two different weight classes. Wanted to fight only the best.
If he was around today, or on the rise i mean, people would hate his guts. "Don't fight Matt, Bj, fight at your own weight wah wah wah. BJ shouldn't be allowed to fight for the title wah wah wah."
