I don't think that Daley should have been fired and banned for life from the UFC. But I do agree.. I think Dana did it to send a message. I don't think he would have done this if it were one of his top fighters like Brock or GSP. Sad to say, but Daley, even though he is a good fighter, is not a fan favorite yet. So it was easy for Dana to let him go because people don't buy pay-per-views to see Daley. And so Dana let's go of a fighter who is still building a fan base and sends a message that the UFC is not like Stikeforce.
Almost forgot: I do think that Dana should have enforced some type of punishment on Nate. He represents the UFC no matter where he is or what he's doing.
