If I were him, I wouldn't. I'd continue to show a bit of spirit about my team. "Yes, we're struggling, but we'll build a winner here. And as for James, need I remind you that he's had championship contending teams before, and he's yet to deliver on one, as we here well know. WE intend to win one as a team, rather than go somewhere else to have somebody else win one for us."
I'm sorry, but I don't understand why everyone is ridiculing Gilbert. He's proud of his team; he's a fan. I would *WANT* him to be confident and to remain optimistic and competitive.
And as for LeBron, I'd be careful about saying "Karma is a b----." He might be right.
