If we are in fact in the top three, we most likely will not know until the #5 pick is announced. If the #5 pick is announced, and we haven't been called yet, we're top three. Additionally, if we haven't been called yet and the Wizards go at #7, or the Raptors go at #6, then we're in.
It can actually get pretty complicated. Just basically root for everybody to get their exact position up through #9, then root for "not Kings" 8-5.
