- They're not less valuable, just less successful. Replacement value
- measures value, while average value measures relative expected success.
-
- Thought experiment: Dave posits that "value" is measured by average value.
- Therefore, an "average" starting pitcher, 200 innings pitched, 12-12 W-L,
- 3.70 ERA, is worthless. But this is clearly false. By definition, such
- a pitcher would be wanted by at least seven of the fourteen NL teams, because
- he would be better than *their* average pitcher; 5-6 others would be very
- happy replacing their #5 pitcher with Joe Average. I daresay that well over
- half of the last twenty World Series champions would want Joe Average
- on their team. Joe Average has some positive value. The value of Joe's
- contribution is his contribution minus the opportunity cost of using Joe
- Average. The "contribution" may be zero, because he's "average." But the
- opportunity cost of using an average player isn't the opportunity to use
- another average player -- it's the chance of using a player who is *below*
- average -- the "replacement level" player. There aren't Joe Averages
- around for the pickings. Talent in baseball is off the right end of the
- curve, and the average player is still at a narrow level of the curve.
-
- Thought experiment: Barry Bonds gets hit by a bus. Is a team with Greg
- Vaughn in LF any better off now that he's become "above average"? How much
- more would a team be willing to pay for Vaughn, given that he's above
- average, whereas before he was below average?
