Projecting players is difficult and professional scouts and player-development staff build careers doing so.
No one on HF except for a few would be qualified to do so.
The Casual fan can only look at stats and prorate based on that with sample size defining the standard deviation and level of confidence metrics.
If a casual fan has "a take" on something that goes against the stats, he is either a fool, or one in a thousand who could probably make a legit career out of it with an NHL organization. Which do you claim to be?
Yes it's difficult but it's very possible. Of course, people doing it professionally have a lot more time and resources to do it better and yield better results.
Who knows how many people on HF would be qualified to do so? There's a lot of knowledgeable people on this site and many with a great "understanding of the game" (can't comment on "the eye for the game" obviously). There's even people with scouting and pro playing experience.
Yes most people will be "casual" because there's only a certain amount of time you can invest into it. Most people work, spend a lot of time on social medias, video games, drinking, family, etc. I don't do any of that (or at least anymore) outside of family stuff. I don't really work much because I have been good at "projecting" stocks, crypto, real estate and even hockey cards. I also haven't been following any other sport (outside of World Cup/Euro) so had a lot of time to invest in hockey as it has been my main interest through the last 3 decades, playing, watching, researching.
I still consider myself closer to a casual fan than a pro obviously but I would say an amateur with extensive experience. I have been projecting players correctly (and uncorrectly) for a long time; not talking about obvious high end picks but guys like Duncan Keith, Keith Yandle or Erik Karlsson for example. Speaking of EK, I bought pretty much all his valuable rookie cards on Ebay when they were made available. Eventually sold most of them, made 30 K$ profit in the process (and still have several valuable ones). I was pretty confident the guy was going to be damn good so I threw a lot of money in him. I did that with several players. Sometimes I was wrong, sometimes injuries derailed the player, sometimes I did very well.
You can take me as a fool if you want and I don't know if I could have made a legit career out of it. I was an executive in sales/management at 28 y/o so who knows? Hard to know if you never tried.
Anyway, not sure why it derailed to this but all I am saying is if you are trying to project a player, your evaluation can't just stop at "sample size". These players both had a development curve before that.
