Last week, I ranked the top 100 prospects and all 30 farm systems heading into the 2021 season. Now it's time to go deeper with my team-by-team rankings, starting with the American League.
A quick refresher on a key term you'll see throughout the team lists: Future Value, shortened to FV hereafter, as a term that sums up the value of a player into one number. It's graded on the 20-80 scouting scale. A low-end everyday player is a 50, which correlates to 2.0 WAR; a well above average position player, No. 3 starter or high-end closer is a 60, or somewhere around 3.
