BJ Penn is a natural LW. Let that sink in. He was more concerned with challenging himself as opposed to protecting his legacy by staying in one weight class after he'd cleaned it out.
As for losing to Hughes (who he also beat twice, Forrest) and GSP (who you think is the best all around fighter in the world - and who oh by the way is MUCH bigger than Penn) - there's NO shame in that. I'm sure if GSP had nutted up - and then got KO'd by Anderson Silva back in the day - you would have forgiven GSP for losing.
Penn has never been finished at 155. He has three losses - all by decision, and two of those were ... close (the first loss to Edgar was utter bullshit for what its worth). And he's never been finished by Matt Serra. You see how I can use some obscure fact that has nothing to do with this argument, so I'm sinking to your level.
Penn has the better overall skillset. GSP has the better resume (if Penn had stayed at 155 for his entire career, he'd have a resume which would rival GSP's)
I'm sorry, what does "natural 155" mean? Does it mean that he was walking around at 155 all his life and wore a fat suit to fight at 170?
Is that why his cardio was notoriously bad- because he didn't have to cut weight?
That's BS. This guy used to fight at MW. He made his name at WW, and got brutally beat, so they sent him to 155 where there no practically no stars at that time, and rebranded him as "natural lw"
No, Frankie is a natural lightweight. BJ is not. In fact Frankie has a much better all around game than BJ. Frankie was outwrestling these HUGE 155pound wrestlers, and boxing everyone from any style.
But as he was chased to 155 because he had back-to-back losses at 170, he was chased back to 170 because well, he had back-to-back losses at 155. But he got thoroughly dominated there too.
That's why BJ Penn is returning at 145. There's just no other division that he can enter. He's bean beat the F out of 155 and 170. Dana probably told him he could fight but only at 145.
Props to BJ for pioneering the 155 division. Basically it was a dead division before BJ showed up. It's now the most stacked division. Good on BJ.
But seriously, he's no where near being one of the best of all time. He got murdered boxing with Nick Diaz. He got wrestled to death by GSP. He got grappled into tears by Jon Fitch.
And Rory basically sent him packing. You can't call a guy like this the best ever skill-set in MMA.
Seriously.
All this 'he fought big guys to test himself...' nah, that's bs. Like I said, he kept cutting down weight classes, and now he's going lower than anyone ever imagined.
He's not a Roy Jones type of guy who started light and kept moving up, all the way the up to prove himself.
Aye, anyways I'll believe that BJ can make 145 when I see it. A natural lightweight should make 145 pretty easily... like how Frankie did.
