EN goals are sometimes harder to get than regular goals. I think a goal is a goal. I see players get robbed all game from a goalie, have like 6 SOG, and then get awarded with an EN goal.
Only thing that annoys me with EN goals is when a player makes a bonehead play by causing an icing trying to shoot for the EN and misses. This, when your team is up by only one goal, with plenty of time left on the clock for the other team to even things up.
I think what impresses me the most with Grabner is he is scoring these goals with no PP time. Granted not everyone can succeed on a PP, where as a lot of players actually do depend on them to score.
