They obviously interviewed GSP, Matt Serra, Dan Henderson, Costa Phillippou and Chael Sonnen and no one else.
In case you didn't know, Costa and Weidman don't train together anymore. I'm really glad they made that move. All we need now is for Georges and Rory to end their bromance.
Dana is a hilarious guy. I heard him in an interview like 2 weeks ago raving about how honest he is.
