Fantasy draft season got me thinking about how unpredictable prospects can be, which got me to thinking about the most out-of-nowhere prospect in recent history: Albert Pujols. Pujols seemingly came out of nowhere in 2001, eventually finishing 4th in the MVP voting. I don't remember thinking about him at all before the season started. He went undrafted in my 7 team NL fantasy league, which means that 210 NL players were deemed better options than Albert Pujols.

My friends and I weren't the only ones who slept on Pujols. The Cardinals drafted him in the 13th round in 1999. He made his pro debut in 2000, enjoying an excellent year in A ball with a line of .324/.389/.585. Still, none of the experts ranked him as an elite prospect. Baseball America is the leading source on baseball prospects. Three of their experts wrote separate prospect lists in BA's 2001 book. The highest ranking for Pujols was #39. Baseball Prospectus ranked him 29th (right behind Hee Seop Choi, just ahead of Adrian Gonzalez), but part of the reason he was even that high was his excellent defensive performance according to their metrics (I'm pretty skeptical about their minor league defensive figures). John Sickels was the most impressed, giving him an A- and rating him as the Number 18 prospect in baseball (right behind Marcus Giles).
I realize that ranking prospects is a difficult task, but it's still hard to believe that none of the experts realized how good he was about to be.
