GSP is a coward.
I find it hilarious that he couldn't talk about Anderson at all, basically did and said everything he could for Dana to downplay the superfight which he was pretty much set on making, then days after Okami-Silva is booked as a result of GSP's apprehensiveness, all of a sudden he can beat GSP?
As for Shields, far from an iron chin. It is solid, but he's been stopped before, he's been rocked many times over as well. Anderson is not Dan Henderson...he would finish the job. Period. Always has.
