Thoughtful column from Damien Cox in the Toronto Star asking that the NHL put goalies, snipers on level ice. The crux of his argument:

Whereas a prime scoring chance once came from a launching pad of approximately 1,500 square feet in the offensive zone, that area has, over the past decade, shrunk by almost 50 per cent. Letting goalies get huge, in other words, has artificially shrunk the rink.
Increasing the size of the nets will not only reset the correct ratio between goalie and available net, it should force defenders to again move further from their crease to defend.

Makes sense to me!
