This is the perfect example of a cherry picked statline to construct a biased narrative while ignoring context.
Only 23 goalies in NHL history have over 350 wins.
Furthermore, The NHL draft didn't exist in its modern form until 1969, when teams could no longer sponsor junior players and sign them directly, as had been the case up to that point.
There are 5 goalies with 350+ wins that are pre-draft era, Sawchuck, Plante, Esposito, Hall, and Vachon.
So only 18 goalies in the draft era have 350+ wins. That's an incredibly small sample size.
In a sport where you have 12 forwards, 6 defensemen, and 1 goalie on the ice at any given time, it makes perfect sense that success in goal would be much more of a crap shoot.
If you want to make a legitimate point use your same metrics for every other position given your criteria and adjust accordingly. For simplicities sake, a forward has 12x the chance of getting in a game over a goalie, and a defensemen 6x the chance.
How many forwards drafted in the first round are top 23 all time in goals or points vs how many played 72 games or less NHL games?
How many defensemen drafted in the first round are in the top 23 all time in goals or points vs how many played in 36 or less NHL games?
Compare those ratios to what you found with goalies and see if there's a significant difference.
