Pedro Carrasco, the MMA news director of BJPenn.com addressed the bizarre tweet on the MMA forum the UG:
"Pedro Carrasco - and there is a reason why he posted it, He is fired up because now that the holidays are over and a lot of his post-fight distractions are behind him he has nothing to do but think about things and he is not happy with the way he performed in his last several fights.
I am not here to make excuses for him, but I am pretty sure people, at least with some sense of intelligence, can identify that the BJ that fought Edgar, Fitch and Diaz was not the same Penn that fought the Diego's and Florians of the world
Things changed, but as it sits right now, he is back. That killer mentality and fire is back and it's been brewing for a while now and today's tweet is a result of it just boiling over!
Expect more from Penn to come for sure! "
