I think Serra handled the cornering poorly, but it wasn't enough for me to dislike him about.
I think talk about him being "unprofessional" is blown out of proportion.
1) His profession is beating people up
2) His opposite coach has ripped his abilities to do his job, and no one blinks at that, but in any other profession that would be the height of being unprofessional.
3) The corporate face of the UFC thinks being professional means being able to use the "F" word as every part of speach in a sentence.
You're hopelessly hopeless and I hope so, for you.
