So what does the worst best goalie in the NHL look like?
I am pleased to introduce to you, the one, the only: Cory-Carey Holtby-Lundqvist!

Obviously a lot of these attributes will be false positives, as well as some false negatives. Because certain very strong attributes can presumably make up for lacking in others. And because all these goalies have such high CA/PA there will be a lot of attribute inflation. Presumably having 15 Adaptability isn't key to being a good goalie. But the lowest of all 4 is 15, because when a player has that high CA/PA a lot attributes that don't need to be high will be just because of the sheer amount of available attribute points. These goalies are hand crafted to be some of the best goalies in the game though, so they also won't have any glaring weaknesses. My personal takeaway from this includes the obvious parts: Looking for high consistency and highish temperament/pressure in the scouting report and making sure the Mentals are within reach for Anticipation, Bravery, Determination, Teamwork and Workrate. The others I prefer if they make the mark. But I won't call a low flair goalie undraftable, nor a low influence one.
On the Physicals side the standout attributes are Agility, Balance and Stamina. The others are low enough that a goalie with high enough PA will hit close enough to those marks as long as they don't start at 6 or less. For Technicals the standout attributes are obviously Reflexes and Positioning. yes glove and blocker are high, but they will be high on any goalie with high enough PA. So I don't really care about how high those are when I draft someone. Because they are key goalie attributes so they can grow by a very large amount from age 18 to age 23. In the case of my Carter Hart both grew by 10 from age 18 to age 23. 10->20 Blocker and 9->19 Glove. And even most fairly poor backup newgens/regens will be sniffing at 16 to 17 in both, even when all the other attributes are in the trash.
If we look at Nino33's huge test of attribute growth in -8 and -9 (primarily) players from way back we can reverse-engineer how high their mentals need to be when we draft them to meet the minimum requirements by the time they are in their prime. In 1.4 there seems to have been a fairly noteworthy change in how mentals grow, especially in high PA players. So I'm not 100% sure those results are accurate anymore. But drafting goalies is more art than science anyways. We just need a ballpark value to help us spot which goalies have a 0% chance of becoming a good starter based on their draft day attributes.
The mental values needed thus ends up being roughly the following:
Anticipation: 17 - 2.96 = 14 to 15 is a reasonable Anticipation range. You will almost never see a newgen/regen with this.
Bravery: 13 -1.26 = 11 to 12 is a reasonable Bravery range.
Determination: 16 - ? = 15 to 16 is a reasonable Detemination range since it almost never grows.
Flair: 14 - 0 = 13 to 14 is a reasonable Flair range, because it never grows. But it's probably not required, just a CA inflated attribute.
Influence: 11 - 4.38 = 6 to 7 is enough due to the massive growth. I'm not 100% sure how the influence of a non-captain affects your team. So ignore as you see fit.
Teamwork: 15 - 1.6 = 13 to 14 is enough. I've seen a 3 point gain from age 18 to 25 in my goalie, since it's affected by training. So as low as 12 could be fine.
Work Rate: 16 - 1.23 = 14 to 15 is a reasonable range.
Most draft years there will be 0 goalies who meet even half these criteria, it's pretty depressing to try and find a good newgen/regen goalie. Because there is always at least 1 massive hole in their mentals or hiddens or positioning or reflexes or agility of balance that makes them fall short. A skater can make up for a hole in his game much easier. NHL goalies have to be so close to perfect that even a single attribute being 1 to 2 points too low just ruins them. Lord knows I have the number of so many top end goalies in my save. Because if their reflexes/ant/agi package isn't flawless you can almost always get them to .900 or less by using low or 5-hole shot targetting. The AI seemingly won't shot target you, but one of these nights all their shots will randomly go low/5-hole anyways and your goalie will single-handedly lose you that game. By trying to hit these minimums you can have a goalie with the most complete game possible. He will still most likely need monster PA to become a Vezina candidate, but with the wrong mentals/technicals/physicals even a 180 PA goalie can be a 1B at best based on performance.
For those that prefer more visual representation, here's my 5x Vezina, 4x Conn Smythe goalie as he looked when I drafted him, and again at age 25. It gives a good idea of how much you can expect things to grow. He's most likely going to gain a bit more in the way of mentals at age 27 and possibly 29 as well, but it's not guaranteed.

Clearly he misses the mark on several attributes. But not in any of the core ones.
Hope this helps you in your goalie drafting!
