Stop thinking that projections are REAL. They are not. They are estimates. Even at $20M ADV scouting, you're just looking at GUESSES.
Look at it this way: You're the GM of a Major League franchise. You get scouting reports from your minor league coaches, coordinators & advance scouts. You're trying to GUESS what the player in question will develop into 3 years from now. Are you SERIOUSLY going to be upset that Joe Smith's scouting report was a few points off (high or low) when he was 18? If yes, you should quit this game right now and start selling insurance. Because the actuarial tables are useful, concrete projections. If not, you should figure the guy won't develop 30+ ratings points in every category and then be pleasantly surprised when he actually develops 24 of those 30 "projected" points. If a player "has to hit his projections to be useful" he's NOT USEFUL.
Good lord, I am really sad that more people haven't looked up "projection" in the dictionary and seen it's synonyms: MIRAGE, GUESS, ESTIMATE.
