Prospects are the best and worst part of baseball. The hope that they can inspire for the future can be undone in the blink of an eye, leaving a franchise scrambling to figure a lot of things out.
By their very definition, prospects are not guaranteed anything. As long as there has been a farm system in baseball, even the best players have failed moving up the ladder and less-heralded players can surpass the most optimistic expectations.
Looking where baseball is at right now, and the current crop of top prospects in all 30 farm systems, the game has never been more fun and exciting than it is now.
Two common terms that you will hear when it comes to prospect evaluation are "floor" and "ceiling." Ceiling is the best and most optimistic outcome for that player, while floor is the most likely outcome.
For instance, Texas' Jurickson Profar and St. Louis' Oscar Taveras, the top two position player prospects in baseball right now, have MVP-level ceilings and floors of everyday regulars. The odds of both reaching that ceiling in their respective career is incredibly unlikely, but they have the talent to get there.
As we look at each team's system at the start of 2013, here are the players--one from all 30 teams--who will have the most difficulty living up to their expectations.
