Marbury and Eddie have great on-court chemistry and only seem to be getting better, so I'd say definitely, if he's willing to sign for $2 mil or less (which is a fair value for what he's given us).
I want to see Marbury succeed as a solid guard off the bench, ideally with us. From what I've seen I believe he will continue to give us better and better minutes with more time to get in shape and get used to how we do things. As long as we don't pay him much, if he ever becomes a problem again, it'd be easy to get rid of him.
