The problems with goaltenders are that we only have 30 starters in the NHL. Meanwhile we have some 360 odd forwards and 180 some odd dmen. As risky as it is to take a goaltender, it's a necessary risk. Most teams don't trade away Stanley cup winning goaltenders (Quick, Fleury, Ward, etc all with their respective teams). I have no problem drafting a goaltender in the later stages of the first round or in the second.
Henrik Lundqvist, 7th round pick
Pekka Rinne, 8th round pick
Jaroslav Halak, 9th round pick
Ryan Miller, 5th round pick
Niklas Backstrom, undrafted
Jonas Hiller, undrafted
Antti Niemi, undrafted
Miikka Kiprusoff, 5th round
Brian Elliott, 9th round pick
Evgeni Nabokov, 9th round pick
Sergei Bobrovsky, undrafted
Sure, there are also plenty of 1st, and 2nd round goalies out there, but I'd say there is no reason to throw out high picks for a goalie.
