One way to possibly create more consensus around here is to properly classify the perspectives as either speculative or pragmatic. All perspectives are technically speculative, but here we could classify speculative perspectives as those that rely more on logical possibilities and less on strong evidence. Alternatively, pragmatic perspectives would be the opposite, relying heavily on what the evidence suggests and less so on theoretical possibilities.
We can use some of my takes to help illustrate this point. For example, I have made the comparison to Tom Wilson. Now there are likely some stylistic aspects of their games that makes comparing them questionable but let's just focus on 3 key variables here. Those variables are: 1. Will Boucher be able to hit like Wilson? 2. Will Boucher be able to fight/intimidate like Wilson? and 3. Will Boucher be able to produce points like Wilson?
The first point actually has a strong overlap to both the speculative and pragmatic perspective. Will Boucher be able to hit like Wilson? Yeah, probably. Boucher has already proven the ability to be a punishing hitter and to track player trajectories to set up open ice hits. He is very physically strong and athletic and seems very dedicated to further his development in the future. With that stated, we know Wilson has a size advantage on Boucher so that could influence his ability to make equivalent hits at the NHL level. Could Boucher end up being a similar weight and having similar strength and power to Wilson? Yeah, possibly. It is unclear if that will happen but it is certainly a possible outcome and there is a reasonable degree of probability for believing it will happen.
The second point is highly speculative. Will Boucher be able to fight/intimidate like Wilson? Thus far the evidence doesn't really support that as being a likely possibility. Boucher has had two fights in the OHL and he has done well but he doesn't have a reputation of being a feared fighter and hasn't established himself as some kind of heavyweight enforcer. If he continues to get stronger and more powerful and start training boxing seriously there is a decent chance he could be very intimidating heavyweight fighter in the NHL. But that is purely speculative because it is only a possibility. Maybe he does, maybe he doesn't but it makes sense for people being pragmatic to assume he won't be that.
The third point is unclear. Will Boucher be able to produce points like Wilson? That we don't know. Boucher has some raw skill and there is a decent chance his peak upside could be a 20+ goal 40-50+ points player but there are questions on whether that is attainable for him. Is his current production trending in a way comparable to Wilson at the same age? No, it isn't. His production is comparable to Wilson at a year younger than his current age. Should his current production gives confidence that he will eventually become a 20+ goal, 40-50 point player? No, it shouldn't. His current production suggests a much lower upside than that. Could he still achieve that upside? Possibly. There are a lot of factors that could have negatively influenced his production this season and he could make some meaningful improvements in his game in the offseason or over the course of his development. Should we have the expectation that he will eventually produce that way in the future? The pragmatist would say no because that is not based on what the evidence is suggesting but instead based on theoretical speculation.
I could add more or make comparisons to different players but I think what I have written has illustrated the point I was trying to make. The pragmatists aren't wrong with their perspective as they are relying heavily on what the evidence is telling them. It can come across as pessimistic to people who are thinking in a speculative way as they are considering more theoretical possibilities and don't feel the need to be so constrained in their projections. Those speculating are going to look foolish to the pragmatists as the beliefs are not based on strong evidence. That is part of the risk of speculation, if you are correct you look like a genius and if you are wrong you look like an idiot. We will only know if the speculation is right in the long run so the speculators are going to look like fools and then either be confirmed as fools or if they are lucky get to look smart and insightful.
