Tank 

In professional team sports, it means to "lose purposely" in hopes of getting a good draft pick for the upcoming season. Of course no one on that team will admit they are doing it purposely.

The Carolina Panthers are tanking the 2010 NFL season because they want Andrew Luck from Stanford quite badly!
