Getting back the third spot will not be easy. In the case of a 4-way we won't have the advantage because it goes to the division winner. (The other teams play all in the same division, so by definition one will be the division winner.) And our programme is not easy (Portland, GSW).
Charlotte seems to have the best programme (Philly, Cleveland, Brooklyn, Orlando).
Having said this, we play Atlanta, Charlotte and Miami at the end, so in a way we hold our destiny in our hands.
Personally, I would rather have the 6th rather than the 4th or 5th spot, but from what I remember from last season, CBS is not into this kind of tricks.
PS: I am writing this on the 31th of March so several of games mentioned in the first post have already been played.
