I guess GSP and Dana White haven't done a good enough job of publicly communicating that GSP wants to fight Diaz to settle the bad blood from last year and that GSP-Diaz is the fight that the fans want to see more.
If I know why this fight is happening and Hendricks doesn't, then the problem isn't in the communication from the UFC or GSP and his camp. The problem is that Hendricks needs to get his head out of the sand. Maybe he's let his ridiculous beard grow over his ears.
I can totally understand Hendricks' point of believing that the #1 contender should get the title shot, but it's one thing to disagree with the decision. To claim that he doesn't even know the reasons for it is a completely different story.
Maybe he's trying to get GSP pissed off because he saw what happened when Nick Diaz called GSP "scared".
