They've gotta go with Brooklyn - it would ensure a rabid following amongst Brooklynites, and to call them the New York Nets would doom them to forever being "that other New York team".
Plus, (and maybe this is just the former Brooklynite in me), I have to think that there would be more merchandising potential in the Brooklyn name. New York already has, what, seven other pro sports teams?

As a casual Raptors fan who watched Bargnani "play" for the last few seasons, I'm happy to see him go. I give Knicks fans two games before they lose patience with his guy and his completely non-existent defense.
