I'd have to think Jarret Bush will need to really show something to stay.
We heard all this talk about his potential, how he had the tools to be a great CB. Unfortunately, it looks as if he made very little progress as the season went on.
As for Ferggie, Manuel, and KGB I don't see them getting cut even if they have a horrible camp. Manuel is the starter as of now, and the most experienced safety on our roster. Ferggie, I think, offers too much value in other departments besides Offense to be cut, and I just don't think we cut KGB given that we have no adequate replacement.
