I think they will almost certainly get Marc Gasol. They will probably sign Jimmy Butler to a max offer too, but the Bulls will match. Not sure what else is out there, unless you believe LeBron will opt out and go to a team that currently has the worst record in the NBA because Phil Jackson and Carmelo Anthony are there. Edit: looking at the FA class there are some good targets, Aldridge, Gasol and Rondo are the "max range" unrestricted FAs available. LeBron, Love and Wade have player options, while Leonard and Butler are restricted. If you go beyond that level you get guys like Al Jefferson, Dragic, DeAndre Jordan, Milsap that might work as secondard pieces, but not really the level of players that the Knicks want to be clearing cap space for. All of the guys with player options will opt out as the cap is going to rise significantly due to the TV deal. Could you imagine if LeBron, Love, and Wade went to the Knicks? LBJ would be murdered the first time back to Cleveland if he leaves them a 2nd time, particularly after all of the "coming home" nonsense from this past offseason. That would be fantastic entertainment.
