Prospects can be a difficult thing to rank. They come from all kinds of different leagues, levels and teams. Each position demands different kinds of play. Performances can vary depending on ice time or health. Global pandemics wipe out entire seasons for some. It’s difficult to really project a prospect and how good they may become if all goes well (and it seldom does) compared to guys of different ages and stages in their development.
And then there are goalies. Most people have a difficult time assessing a fully mature goalie in the NHL, much less also factoring in being a prospect and trying to guess how good they may be.
