It is footage of a prospect. Not everyone has access to watch these games on television or a streaming service, and some of those people would like to see Boucher play. Those same people would like to make their own evaluations of Boucher based on what they see and not rely on other people's assessments. This is more reflective of what scouting is actually like. It is watching a player closely and looking for subtle details in their game, breaking apart skills and attributes to how they are developed over time and the types of progression they go through and then using that conceptual model to assess how a prospect is actually performing and whether or not they are progressing on those development paths.
A lot of people would likely find actual scouting to be very boring. They want immediate gratification; the flashy highlight that is blatantly obvious for everyone to see and for everyone to assess. They don't enjoy the difficult task of hunting for subtle details, sifting through the ambiguity and attempting to formulate accurate evaluations of the significance of what is occurring. In every single game and every single shift, every little detail is actually significant, and quite often of profound significance. Teams and players reveal their patterns all the time. These patterns help uncover their weaknesses which later become exploitable opportunities.
From an individual player standpoint, at the junior level, each game and each shift reveals how well a player is going to be able to adapt to the NHL level, how much of their game is transferrable, what tendencies are they going to have to unlearn and will they be capable of doing that unlearning. Troy Mann has even stated this before, that at the AHL level he has to coach the junior out of the player. It takes quite a bit of effort to make such assessments. A person needs to see the patterns of success and failure at the NHL level and then see the patterns of success and failure at the junior level and then determine where the gaps lie. There are patterns of success at the junior level that are actually patterns of failure at the NHL level, there are also patterns at the junior level that don't come across as obviously successful but are actually very strong signs of being successful at the NHL level.
The point is that some enjoy attempting to embark on that difficult task, to really attempt to analyze and breakdown the game, whereas others might be more satisfied with watching highlights.
