Who will go #1 in the 2007 nba draft if greg oden, kevin durant and branden wright don't enter?

I have a strong feeling those 3 might stay another year since the haven't put thier names in the draft yet, but then again they still have a few more weeks. Plus one more year of college will be good for them, not only on the court but off it as well. Who do you think will go #1 if those 3 don't enter into draft
