Bingo....If you are signing for less than a couple hundred grand, then you are simply not a prospect. You are just a roster filler there to make up a team so the prospects can play other teams with a few prospects (like Lucroy was) getting ready for the Show. If a roster filler (organizational player) surprisingly develops into a prospect then that's just icing on the cake.
There are 700 MLB jobs and they draft 1500 kids per year. They only need about 100 new players per year in the Show. Nearly all players should finish college, get their degree then play pro ball, if they want to and are asked.
