It is one thing if it is deflected in but when you score on yourself it is bad.  The Dallas Stars recently scored on themselves with a empty net goal against Ottawa.

According to SB Nation, former Red Wings and current Dallas Stars forward Jiri Hudler scored on his own goal after a drop pass back to the net.   The play started with a delayed penalty so the goaltender went off the ice  that left the goal wide open and well disaster for the Stars.

A few passes and then the drop pass pack to an open net and goal.   A highlight that the Stars would like to forget.
