I think all of these people are long shots. Why would they want to play for the Knicks???
What's more likely is that D'Antoni will try to sign some of his Phoenix players: Raja Bell, Stoudemire, Nash and Q or Joe Johnson.
My idea of getting better is, rather than signing a bunch of big names, to carefully draft players at deficit positions, carefully decide which players to keep and which to drop, and then, after all that, when a solid team has been assembled, maybe trying to get to the next level, by adding a big name player to the roster.
They should be trying to use this money to get a bunch of solid players, not just one or two max players. This whole buy-your-way-to-victory approach will backfire. Mark my words.
