David Aldridge appears to suggest here that they are each on the table for the Wizards in exchange for Blatche. Can either of these guys improve our team? I think I could make an argument for Tyrus Thomas, but I don't know about Villanueva.
While Tyrus's contract is horrid, he is terribly athletic, and might be an effective player slotted in next to Nene or Okafor. He would also provide insurance in case one of Okafor or Nene goes down with injury, and either Vesely or Seraphin don't make the "jump" that we are all hoping for.
