I agree with Big Mike, and was going to post the same thing. If the goalies leave the crease they should be fair game just like anyone else. I like moving the goals closer to the end boards, and I think they should do away with the 2 line pass. With that said, the only one I'm adament about is making the goalies fair game.
I don't think the changes are because of ratings. If it was strictly for ratings, the NHL would encourage fighting. Fans love a good fight, just listen to the fans on that video! As a matter of fact they SHOULD get RID of the instigator penalty! That will allow teams to police themselves and reduce cheap shots from guys like Kasparitis and Domi..
As for the american ratings, I read an article earlier in the year, and next to NASCAR, the NHL had the largest tv growth in U.S. sports.
