Excellent post and agree with all of your points. There are other factors as well: Overexpansion, with thinned out the talent across the board, thus teams attempt to compensate for the lack of pure talent by playing a more defensive style...goalie equipment has become bigger, and goalies are now looked at differently now then they were years ago, it was never really a "glamour" position like it is now. the success of Hasek also assisted with paving the way for an influx of European goalies, so the talent level is higher at the position.
Plus the players are bigger, maybe a larger ice surface is needed?
Im not sure what the answers are, but something has to be done.
