What the NHL is doing is making a big statement to get the attention of the ADD riddled US population. Americans are scoring junkies, and that is why the growth of soccer has been so slow (well, at least until the southern border became nothing more than a line in the sand).
The US is money-ratings money and ad money are what fill a league up with superstars making their zillion dollar contracts.
It's more exciting, but I'm sure a lot of old time purists are fuming, and I can certainly understand why.
