As many reading this may know, BJ 'The Prodigy' Penn has officially retired from MMA. He even went so far as to say that he shouldn't have gotten back in there. The last legs of his career weren't in his favor. After losing twice to Franky Edgar, he went back up to 170 where he got a draw against John Fitch, beat Matt Hughes, and then lost to Nick Diaz and Rory McDonald. His career concluded with a third round TKO loss against Franky Edgar, completing their trilogy. It's important though, that in spite of how his career ended, fans, especially the newer generation that may not have been around to witness it live, would do well to remember him for who he truly is and what he represents in this sport. BJ Penn, in addition to being truly gifted, epitomized the Budo of the sport. He would fight anyone, regardless of weight, and though the results of these fights may have been mixed, there's zero shame in being a natural 155lber dropping a decision to Lyoto Machida at Light-Heavyweight.
He remains one of only two fighters to ever hold titles in two weight classes, 170 and 155. Randy Couture is the only other to do that in the promotion's history. He is a true fighter, in every sense of the word, and even his last fight represented that perfectly.
He wanted to know if he could still hang with the UFC's elite, and rather than hang back and wonder 'what if?' for his remaining days, he sought out Edgar, never being able to let go of the two losses he previously suffered to him, and then went down to 145lbs, which he had never done before, simply to fight him again. It didn't go his way, but to someone like BJ, that will always be better than living his life wondering what could've been.
