One of the old standbys of scouting reports that enter the public sphere is comparison scouting. It's easier for fans to visualize what a player can be if you can compare him to a similar player.
With recent advancements made in analytics and within scouting departments in general, there has been more effort to make those comparisons less subjective with various models created to see how a prospect stacks up against historical comparisons. One of the more popular examples of comparison modeling is "Prospect Cohort Success," better known as PCS, a system developed by Josh Weissbock and Cam Lawrence, both of whom now work for the Florida Panthers.
