As centres and defencemen are generally accepted to have the greatest value in a vacuum (though I personally lean towards the defenceman on most occasions) I think the debate that remains is pretty interesting.
Taking a quick look through the thread, I see wingers as having "far more value" than a goalie. While that might be true for your bottom-9 wingers vs journeyman #1B netminder, I'm baffled to see how a consistent, bonafide #1 goaltender (think Lundqvist, Price, Kiprusoff, Hasek) somehow aren't considered as better at covering up the deficiencies of a team better than the likes of a star #1 winger (Ovechkin, Iginla, Kessel in Toronto, etc.) If we are to judge the position's value by considering player scarcity, the goaltenders with solid #1 ability should hold far more value than your comparable first-line winger.
