Mm, well, at the end of the day it's all smoke and mirrors. The reality, though, is that he came back for one fight against Bisping and then surrendered the belt rather than face Whittaker or Romero due to colitis. Then, literally a month later, he's suddenly open to fighting again, but at 155.
I'm not implying that any pro fighters fear one another - that's just a brainless and ludicrous asertion. However, it looks as though GSP is being highly selective of preferable matchups, and to that point, I have to agree with what White said a few months back., because as a fan I can only say that if you aren't here to challenge yourself, you ought to stop wasting our time.
