Sure it does. I can go on twitter and say the same thing. Doesn't make it true. His "source" isn't credible.
My point is the 2nd tweet doesn't add anything new or important to what was said in the first. He already stated his "sources" were telling giving him this info...so whether he personally thought Lebron would stay in Cleveland is of no interest to anyone. Additionally, it doesn't provide any legitimacy to his first tweet, which is obviously unfounded based on his unnamed sources.
