I can't make you believe or not believe him, but I think that the reactions of Orioles fans who are familiar with Clark speak volumes. This is a guy who has tweeted out rumors (on a smaller scale) in the past and deleted them when they are wrong. He did leave up the Markakis one which he got wrong, which I suppose (?) I give him credit for?
Anyway, it's fine if you think he could be right, I just don't appreciate when other people feel the need to mock those who don't believe Clark, especially given his track record.
