Projecting individual prospectsPosted by Alex Pedicini
Bryan Smith wrote an interesting and thought-provoking article earlier today over at Fangraphs. Basically, Smith is trying to formulate a method to predict a median future performance for an individual prospect (he used Cubs shortstop Starlin Castro as his example).
This is certainly an worthwhile idea and one that could potentially revolutionize the way prospects are viewed. As we know there is a sizable risk involved in almost any prospect, but if we could somehow quantify this risk we could more accurately project future performance.
One way to do this would be to develop some type of confidence intervals for a prospect's future performance during his first six major league seasons. However, to do this would require estimates of injury risk and potential "bust factor".
I'm not sure how probable or realistic this would be to do but it is still an exciting idea nonetheless. The guys over at Sons of Sam Horn have been putting together something along these lines. They are compiling a "community success probabilities" for Boston prospects. This is a good start to trying to predict a prospect's future role and having a variety of opinions may yield better results, although obviously the younger and further away a player is from the majors the more difficult this becomes.
I'm sure there is plenty of proprietary work done by clubs regarding this type of analysis and for good reason. If a team can narrow their estimates of a player's future ceiling they will be better prepared to develop or possibly trade this player. I expect there to be major strides in this area of prospect valuation and projection as the decade progresses.
