A quick primer to begin: This is not a list of my top overall prospects — Shelby Miller would not lead that list. No, this list exists only to serve those of us in fantasyland. The names that follow are, at this moment, the prospects who have the best chance at offering positive contributions for fantasy owners in 2013. My method here was quite simple: each player was assigned a grade for both potential fantasy impact, and for current opportunity. Those variables were weighed equally, totals were then tallied, and finally, I sorted out the ties and adjusted here and there as I saw fit. Opportunity grades are always tough. At this point in the year, circumstances can shift overnight and a prospect’s ETA can change dramatically (see Miller). My plan is to revisit this list before opening day, and also to keep a running Top Ten Fantasy Prospects throughout the year in order to keep us posted at any given moment as to which fantasy-relevant prospects are next to arrive in the bigs. In any case, this list should suffice for those of us drafting early.
