Iguodala only goes to Golden State if the sixers want him to and the only way that truly works out is a sign and trade for the warriors - so depending on what the sixers would get back i'm not horribly opposed to it.
I am a huge iguodala fan, but i'm not opposed to him going if it improves the sixers long term.
I think the sixers just have to publicly say they'll match anything, look how it screwed pavlovic and varejao...make the warriors S&T if they want iguodala
