Have to think Collins, Burnett and Peprah will be there. Then who?
Bush is an ideal reserve who provides great value on game day. He can come in at CB or safety in a pinch, while being a major contributor on special teams. But, I believe he is unsigned. Will the Packers give him another big contract for a backup player?
They seemed high on Levine at one time, but there is no room for him unless one of the above is let go, or they consider Bush as a CB and keep Levine as the #4 safety. But CB has four virtual locks (Williams, Woodson, Shields and House) plus Lee and Underwood.
Then there is Greco, who the Packers signed and released from the practice squad a couple times. I believe he ended the season on the PS. A big guy at 6'3". There must be something there that they like.
I can't imagine Bigby or Smith being back, but....
