Interesting idea about trading Nixon OS. I think he would fetch, at best, a 4th round pick, and that may well be worth it. To your points, he's a decent CB and a good returner. A trade is certainly something inside the realm of possibility. And the D is already playing well, Atlanta aside, and Parsons should be back soon. Finally, Cisse is playing ok and learning. I love his aggressiveness. I don't know how St. Juste has perfromed so far.
And I agree that being 2-2, 2-3 is not a death sentence on the season. There is a LOT of football ahead. What holds down my optimism is the truly awful play of the OL, and now the loss of the best player in that group, ZBB.
Gluten did what he had to do this week by picking up some retread linemen (with solid pedigrees). I think two of the three he acquired are expected to start at RG and LG today. Zeitler is one and O forget the other. I'll feel better if that can buy Love more than 2.5 seconds after the snap, and if holes can be opened so we really know what Lloyd is capable of. Even Jacobs could not run well behind this line.
To close on Nixon, he seems he is playing better this year due to increased competition.
