Butler OR Gooden
Think about this man. Grizzlies want Dunleavy really really bad and they are one spot behind the Warriors. The Warriors take Dunleavy, forcing the Grizzlies to take either Butler or Gooden. But, the Grizzlies want Dunleavy right? So they trade either Butler or Gooden to the W's with something else. These deals have been made in the past.
Examples:
#5 pick Ray Allen + cash for #4 Stephon Marbury
#5 Vince Carter + cash for #4 Antawn Jamison (damnit we had to trade Vince away
)
