I give the org a lot of flack but all you can really do is listen to what scouts say and run with it.
The more high pick, high ceiling guys you get, the better chance of getting a future MLB hitter.
Your point is exactly why I dont get excited about prospects unless they go ape s*** in like at least double A.
Travis snider was someone who at the time fit that billing in terms of tearing up the minors but obviously fanned out as an MLBer
In regards to hitters specifically I looked up only the first round in the past 15 years and found some interesting things of note
Since 2009, 10 of our 12 first rounders have been pitchers.
Obviously first round doesnt mean auto-mlb talent but it shows we havent been targeting position players as early. The true high ceiling, likely cant miss guys havent been position players so its not a total surprise our 5th, 6th round talent never can make that final leap.
In the end players just gotta produce I dont think our org doesnt know how to develop talent, its just that most talent fails.
Also aaron hill was in the 2003 draft and while his time ended poorly, he had some good years here.
