NY doesn't want to have $8M locked up over the next few years in Carroll and Nazr. Harrington would be good, but I'm not sure they'd want him more than David Lee.
GS is looking for a pg more than anything. I don't think they want another SF or PF, especially a PF with a lower ceiling than the one they'd be giving up in Wright.
Lastly, we wouldn't want Marbury because of the distraction. Yeah, we'd save a lot of money after this year, but we'd also have to convince a big time free agent to sign here but still not be able to offer as much as many other teams. Wright would be nice, but Binelli more or less duplicates Ammo's talent.
Meanwhile, we'd lose one of our best players who has a reasonable contract.
I just don't see it from any of the team's point of view, although NY would probably love to rid themselves of Marbury. Who knows?
