Draft grades for the MLB draft are perhaps trickier than in any other sport. Most of these players, after all, will spend years in a team's farm system, fine-tuning their games before they are ready to hit the major leagues.
Baseball prospects, especially those coming straight from high school, feel more like unmolded clay than you see in other sports, so any draft grade is taking into account value at the pick and a player's perceived upside and little else.
But hey, this is sports, and we need to quantify everything so we can compare, contrast and argue with out buddies who root for a different team.
