I don't know what Troup's propsects for recovery are, but he sure sounded discouraged about them. Chronic back problems don't just go away, take it from me, and I don't have 300# guys slamming into me. I think he's probably done with the Bills.
In other news, I though Heard looked pretty good against Washington. He definitely made a better impression than Carrington to me. I think the 9th DL spot is between him and K Moore. I'm actually the most interested in what happens with Lindell v Potter. I have a feeling that if Potter hits his field goals during preseason that the Bills may cut Lindell rather than keep 2 kickers.
