You're great at spouting aphorisms; you're bad at understanding why I asked what I did.
College-trained players are about 50% more likely to make the majors than high school players at equivalent draft positions.
The numbers seem to suggest that it is more worthwhile to draft college players, so I would hope the Blue Jays take college players.
Here's the thing...I'm familiar with Rany Jazayerli; you apparently are not. Had you read all the way to the next page, you would have seen this. Discussing hitters:
[...]From 1992 to 1999, however, the edge enjoyed by college talents slowly degrades until the two groups are almost equal, with the college set retaining a narrow and perhaps statistically questionable advantage
And pitchers:
[...]But the gap between success rates for high school and college pitcher draftees is much smaller than it once was. No longer is it a grave error -- going strictly by the percentages -- to draft a high-school hurler in the first round.
Oh, and then there's this, of course...
Rany Jazayerli on the "Moneyball Effect" in drafting, in which he concludes that the trend toward drafting college players had rendered high schoolers
more valuable than their four-year counterparts, possibly by as must as 40%.
Which brings us back to my initial question about parameters. Drafting in baseball tends to be prone to trends and fads, each of which create market inefficiencies.
Moneyball was about this very same thing. At one time, college players were grossly undervalued; a few years later, high school players were. Sometimes it's bats, sometimes it's arms. The issue we encounter is that the effects of these trends can only be clearly discerned a few years out...we don't know precisely what is happening until that generation of players has reached the big leagues. And thus why it's important to define a time frame: if you're talking about all prospects ever, you're glossing over so many changes in the prioritization of players that you don't know a **** thing.
