There's an interview in this year's Baseball Prospectus between Gary Huckabay and an MLB executive that demonstrates the ridiculousness of this.
The executive is explaining that (1) most of the candidates that apply aren't qualified from a technical standpoint ("they were fanatical fans who didn't have the fundamentals of real-world analysis") or (2) if they were qualified, they were too pricey ("the cost of bringing either of them in was absolutely ridiculous").
Huckabay: "To me, that's a complete copout. There's no team that hasn't wasted ten times the cost of one of those guys on a bad player contract."
Exec: "It's not that simple, and you know it."
Does Huckabay really believe that a team is going to say, "Hey, that back-up catcher we signed last year who batted .200, if we cut him, and we can afford a top-flight stats guy?" I mean, I like baseball stats too, think they have some value, but I just don't think that's realistic. Later on:
Exec: "I can't justify the cost, the risk, and the upheaval of hiring a Keith Wolner at the salary it'd take to get him, and the other costs and commitments that invariably come with him, or one of the people we already talked to."
Huckabay: "But you can afford to throw away $40 million on crappy player contracts that you'd now like to duck."
Exec: "Oh, be serious. Against, it's not that simple, and you know it. And every time you mention something like that, you either imply or explicitly state that the club doesn't understand the concept of aging, or doesn't know the contract's going to be a rock around their neck down the road. In the case you're speaking of, we knew the last two years of a couple of deals were going to be bad, but we wanted those first couple of years so we could make a run at a title."
But Huckabay never does get serious or respond to the fact that it's not as easy as he thinks it is.
This is precisely why I think the BP guys are out of touch. I don't even find them particularly clever or funny as much as mean-spirited. I'm not going to put down the metrics they use. I think their research dredges up interesting things that probably do have some practical use. But the idea that everything works just so in the universe they've constructed in their minds and computers, I just don't buy it.
