He deleted the tweet but the same article is still up on his site and linked to the new Tweet. I think he deleted it because people were taking it out of context of the article and assuming that it meant a players only meeting to revolt against DA because that's what people want to happen. When, in fact, it's a meeting among the players to discuss what they need to do better.
Either way it's a bad reflection on DA, but it's not the player mutiny that we want it to be.
