Brayshaw kicked a drop kick against the Dogs on the weekend and the umpire called him for holding the ball, the drop kick is dead.
Similarly, the torp is an incredibly low percentage play and dead too. It's very difficult to kick accurately, almost impossible to hit a lead with and it probably resigned to only being viable when bombing long for distance. Even then, there are probably better options. When it comes to the other side of a torp, they are also incredibly difficult to mark.
These days there are rarely occasions where a torpedo would be useful and almost none where it's the best option.
