The prospect score is a percentile of his expected outcome among every prospect in the league: the chance he becomes a regular, times how good his comparables who did became against others at their position. A player who never sticks counts as zero, which is why a long shot with a high ceiling can rank below a safe bet. Goalie projections carry the widest error on the site — goaltending develops late, and there are few goalies to learn from. All Sabres prospects · How the rankings work
