I've been reading Luke Walton and Tyron Lue also. DFisher said he wants to take a year off if he decides to retire from playing this season so you might have to rule him out. Rambis makes the most sense with his HC experience, though his record was hardly impressive in MN he would probably be the best candidate to implement the triangle and Phil's philosophies in NY.
I'd love JVG back but the lack of rumors about him for other jobs tells me he's not interested in leaving the booth for coaching just yet. Someone said the one thing Kerr lacked was toughness and JVG has that in spades.
