It's two fold... you're not drafting in the now as we seen with Harvey, he was raw even by HS standards, raw power, strong arm, unknown future speed after the knee injury (which is the easiest to project), somewhat long swing, and fairly agile. He was drafted with two definite pluses and 3 unknowns, although I consider approach for position players as a 6th tool which at the time was likely unknown/aggressive. Scouting isn't just about driving around and looking at ballplayers, you have to get to know the kids, know their demands, know who'll sign at what slot and who would go to school. You have to know whether or not he's soft mentally, work ethic, etc. If you don't factor signability, you'll be fired quickly. You have to know what other scout think about kids and where they'll draft a kid. You have to fight for your guys the week before the draft, go back and forth with the scouting director and the area guys to determine how it'll likely go. It ain't easy to pick up, beyond what I mentioned, the mechanical side of the game in regards to progression is very difficult to pick up. It takes about 6 years of scouting before you actually have a complete grasp of you're doing. Scouting for the now is pretty easy, scouting for 5 years from now that is difficult. Baseball is won by superstars, to be a superstar you have to have tools to do so. It's up to the scout to see those tools early on, make a correct OFP and draft accordingly and then turn him to the developers and have them progress his tools into future production. It's not either or, the development and the scouting side of the game need each other to do well to be successful.
