For tankers:
We need for Cleveland to, essentially, take Chicago's playoff seat, since there's almost no question they dump Boozer, and go under at this point.
Any improvement to the Magic, Nuggets, and Kings is a net win for us.
The Kings will clearly try to win (having taken on Rudy Gay, as will the Nuggets). The Magic are tanking regardless, and nothing can save them anyway.
If there is even marginal improvement in Denver, Cleveland and Sacramento, the bottom of the pile will look like (in rough order)
Utah
Milwuakee
Orlando
Philadelphia
Boston
The top six players in the draft are all game changers:
Embiid, Wiggins, Parker, Smart, Randle, Exum.
