They might do it because Ted doesn't like to watch talent walk away before a second deal. But as you say, the numbers may work against it. He does have a number of starts, so his price might not be bargain basement.
The only scenario I can picture that they NEED him would involve moving Linsley to Guard to replace Lang (or backup both) and let Tretter start. With a backup Guard, you let Barclay go and keep Murph and the Magictones (Spriggs).
