If it really isn't about the money, the Celtics and Lakers would really have to be high on any of these big free agents lists.
That said, I don't think it is only about the money, but money does play in. If you could somehow convince Lebron that playing with Pierce, Rondo, and Perkins is his best option, I think you could potentially get a sign and trade with Cleveland, by sending back Garnett and Sheed and also taking on Williams or adding in Davis and taking Jamison. That would allow Cleveland to start rebuilding much quicker. Obviously two or three firsts would also go to Cleveland.
That said the chance of any of that happening is next to nothing so there really is no point in talking about it.
