You're probably aware by now that BJ Penn isn't the most popular fighter among MMA fans.
Words such as "sore loser," "cry baby," and "f**k you" have been lobbed at BJ with alarming consistency over the past several weeks.
Depending on whom you ask, this criticism is either highly warranted, or highly unwarranted.
As a huge BJ Penn fan, I can admit that he has displayed some questionable sportsmanship in the past. No question.
But sportsmanship, if you think about it, is just like Einstein's theory of uniform motion, and also like the redneck couple who live down the road.
"It's all relative."
That being said, I have compiled a list of fighters who bring bad sportsmanship (and bad citizenship, for that matter) to a whole new level.
Relative to these royal douchebags, BJ looks like a saint, even on his worst day.
Here are 10 guys who you should always root against, under any and all circumstances. Your favorite fighter should be whoever happens to be fighting these guys.
