This is a pretty good reference position if one were into such things. Moving the spares around has a pretty obvious effect on the cube action. Put doubling player's spare in a worse spot it's a take, put the player being cubed spares in a higher up spot it's a take, anchor on the 23pt instead of split is a huge take, anchor on the 24pt it's a huge pass.
