Why Wasn’t Kole Calhoun a Prospect?
In the grand scheme of things, evaluating a baseball player’s current ability isn’t that difficult. If you have a sampling of their statistics and have a chance to watch a handful of their games, a reasonably informed observer will come up with a pretty good estimate of the player’s current talent level. Figuring out how good a player is right now requires some skill, but it’s nothing compared to having that same information about a player and attempting to forecast six years into the future.
That’s the job of a scout. You get a handful of looks at a 19 year old, you talk to a few people, you glance at some numbers, and then you’re asked to predict what that player is going to look like at 25. It’s a big ask and as a result, there’s a pretty big margin of error. A good scout should be more accurate than a decently competent observer, but no one would expect a scout to be right on every player. There’s just too much uncertainty involved.
One would hope that a scout doesn’t miss any Mike Trouts or bet high on many Jeff Larishs, but they’re going to miss good players and speak highly of bad one’s during the course of their careers. That’s especially true with respect to very young players.
