That's 44 goalies drafted in the first two rounds over the last 10 drafts.
4 starters: Price, Rask, Bernier, Varlamov.
7 backups: Pavelec, Neuvirth, Enroth, Lehner, Cal Pickard, J. Gibson, J. Allen.
1 in Craig Button's Top 30 NHL Prospects as of Jan. 2015: Vasilevskiy (4).
How many of the 4 who aren't starters now are projected to be NHL starters? Vasilevskiy, Gibson, Allen, maybe Subban and Demko? So perhaps 5 if all goes extremely well, which is unlikely.
I think when you look at the data overall, you are talking an incredible bust rate; very very few choices where you can say the team got value out of a top 2 round pick by taking a goalie; and a very small sliver of getting an NHL starter, let alone an above-average player.
TL;DR: Don't draft a goalie in the first two rounds.
