I believe Gomesfan that it's a real account. I'm not sure why Gomesfan would make all that up. Hopefully there really is a trade. I'm sure the teams just didn't want it released via twitter, thats why they shut it down. Just checked, and for what it's worth, the account is back up and the post is still there.
If there is a deal, I would bet it's as simple as Battier for Semih, Nate, and Daniels. Works financially like that. Maybe even a pick going to Houston. It would depend on Keys being willing to waive his no trade though. I would absolutely love that deal.
Houston has said they're not resigning Battier this off season, so he is definitely available to trade. They've also said they're looking for big men. They like foreign players, and I think Semih has some actual value around the league. This trade makes a lot of sense on multiple levels. Let's all hope.
