If you ever doubt that BJ Penn was the greatest lightweight in UFC history, rewatch his fight against Diego Sanchez and see what a motivated BJ Penn is capable of. It’s unfortunate that despite numerous lackluster performances, die-hard MMA fans just can’t stop believing in the proud Hawaiian’s skillset. We’re glad that BJ Penn has decided to un-retire and we hope that all the time off and the new Canadian opponent has rejuvenated his work ethics. It’s probably a good sign that he’s leaving his comfort zone in Hawaii and prospecting AKA as a new home to prepare for Rory MacDonald. For all of you wondering how Jon Fitch feels about that decision, that’s not important, what’s important is what BJ Penn has to say to Jon Fitch about invading his gym.
