Is he now a WR3 with so many mouths to feed in Detroit or do you think once they start double teaming M_jones that Stafford goes back to Tate?
Is he waiver wire material all of a sudden?
I don't think yet, I'd try to keep him around if at all possible. Like you said, defenses may start to shift a little now that it seems he's a forgotten guy. Maybe give it another week or 2 to try and get a better feel.
