Absent injury or a lack of progress, the DL is set as you have it. For now the pencilled in LB's are Babin, Sharper, Foreman and Wong although Wong has been getting some work at ILB this week. Capers says that is preparing in case of injury--training camp will tell us if that is true or they think Peek is ready to start. There hasn't been a whisper of news about McCree working out at SS and given the reporting about Pitts' move to LG and Wong playing ILB some, doubt that McCree is getting tried out at SS.
