Exactly, every prospect is, in essence, a lottery ticket, you can't look at any one at a point in time and say this one sucks and this one is a future star. Do some have greater odds of reaching success? Sure, but all have a ceiling to be fruitful major leaguers. JD Martinez himself was once a lousy prospect. The game is to accumulate prospects that have traits that you believe your staff can develop and profile in line with organizational values, and are upgrades from whoever they will replace in the organization. Most aren't going to make it, but if you keep upgrading at every level, at every opportunity, that's how you build an organization.
