Goalie development is no more finicky than skater development if we compare 1st round picks to 1st round picks, 2nd rounders to 2nd rounders, etc. What makes it seem so finicky is that most goalies are not drafted top 40, or even top 100. A 1st round goalie is no more likely to bust than a skater taken in the same area.
I disagree with that. Goalies have to take a bigger jump than players do when they enter the NHL. If they aren't good enough to play they simply don't get the playing time. Goalies do not have the benefit of being able to play sheltered minutes until they can adjust to the NHL like players do. It is a longer path for goalies to get to the NHL and that means there is more chances for a team to mess something up in development, especially if they get impatient. Goalie development has a much finer balance between giving opportunity and being patient than player development has.
I was curious so I decided to look at the first round of the draft since 2000. I decided to omit the last 5 years because it is too early to form an opinion on those players and goalies.
To determine if a player was a success in the NHL, I decided to use games played. The average career length of an NHLer is about 5 seasons, or about 400 games played without missing a game. I would say at the very worst you want your first round pick to be at this level. For some of the more recent years, there are some players that do not have 400 games played, but currently have starting roles in an NHL lineup and are on track to have 400 games played, so I'll consider these players separately and they will represent the top end of draft success in the first round. There are also a few long shots that may reach 400 games but I considered these negligent to the overall percentage.

In this 15 year period there were a total of 424 non-goalies selected in the first round. Successful first round players lies somewhere between 204 and 247 players or 48% and 58%.

In this 15 year period there were a total of 26 goalies selected in the first round. For goalies, I would consider a starter to at least start half of the season, so if you take the average career length of an NHLer, a successful starting goalie should play at least 200 games. This leaves you with 11 goalies or a 42% success rate. Vasilevsky, Bernier, Varlamov, Price, Rask, Dubnyk, Schneider, Fleury, Lehtonen, Ward, DiPietro.
I will admit that I thought the discrepancy would be larger, although that's not to say the difference is not there. Something else that I found interesting was that 6 out of the 11 successful goalies were traded for a first round pick or less during or before they entered their prime. All 6 of those goalies outperformed what they were traded for after the trade besides maybe Jonathan Bernier. That would leave Vasilevsky, Price, Fleury, Ward and DiPietro* as the only goalies that returned good value for the teams that drafted them. Only 19% of the goalies selected in the first round netted the teams that drafted them good value. That's another lesson in why teams need to be as patient as the selected goalie requires them to be, and why acquiring established starting NHL goaltending through trade still looks like the smarter move.
*DiPietro was not a good goalie.
