A couple/three problems I see with this. I consider myself on the more analytic end of the spectrum here, and I want numbers to back up my management decisions, but I find it hard to believe a ranking of amateur baseball prospects is absolute enough to do more than put them into rough groupings. The 1:1 pick can be a little special, in that some years one player may stand out alone. Otherwise, even at the top you have a group where the best forecasting is still just "well, one of these [four, whatever] guys will probably turn out to have the best Career WAR* [or whatever metric] out of everyone". And then after the team's first pick, the fuzziness only increases; there's not a lot of daylight there between a dozen or more choices. Second, and maybe more importantly, the draft pool money system MLB instituted has a huge impact. If you have identified a few top choices, as the Twins no doubt did, and had a guess for both Career WAR and signing demand, it may be wiser to do as the Twins did. Say your WAR estimate** for Greene is 50 (borderline HOFer) and for Lewis it's only 30 (everyday player for years), but Greene will cost a lot, then clearly you should just go ahead pick Greene anyway, because you can't make up the lost 20 WAR by picking up one or more high schoolers who drop, and whom you can lure with a million additional dollars, with your next picks. But I'm betting that a competent probabilistic forecast would put the candidate prospects much closer in estimated career WAR than that, this year at least. Suppose the best minds in your front office guesstimate Greene 50, Wright 48, Gore 47, Lewis 47, McKay 42, but you've also got your eye on Enlow at 30 who you think may drop due to signability, and anyone else likely still there at your second pick is more like a 20 at best, such as Rooker, then (as actually occurred) picking whoever in that top group will sign cheap enough could give you 47+30 instead of 50+20. I think the disagreements here (or anywhere) on whom to pick 1:1 come down to an assumption whether there is a lot of separation or a little. Precision, separation, and draft pool. These are what lead me away from expecting to construct a predefined ranking of prospects and then just pick the top one at each turn. * Just to be clear, I'm referring to "WAR" very generically here, and not a specific implementation seen anywhere. Simply, "how many wins do you think this guy will add to your standings over the years?" As the analytic type, I do think you have to look at it in approximately those terms. Accomplishing it is the trick. ** And by WAR estimate I mean an average over all reasonable outcomes, including injury preventing a career at all, but also the faint chance of a 120 WAR meaning an inner-circle HOFer. Expectation value, for those who think in those terms. Not simply best ceiling, or best floor (whatever floor means for an untested amateur).
