Those guys should not be hard to replace and Miami won't have nearly as much cash to throw around but they should be able to keep any and all of those guys if they want.
Breida seems like a guy they would want to keep since I doubt they traded a 5th round pick to rent him for one year.
That was my first instinct. This regime is most likely to sign the one guy it pursued.
I don't view any of them as imperative. We know they liked Godchaux more than Vincent Taylor. Whether they like Godchaux long term is another matter entirely. He doesn't make enough plays for a smaller interior guy. There are hints when they draft someone like Raekwon Davis.
