<strong>The</strong> other thing to notice about this figure is how well the curve fits the data.<br />

<strong>The</strong> individual trades, represented by the dots, lie very close to the estimated<br />

line. In empirical work you almost never get such orderly data. How could this<br />

happen? It turns out the data line up so well because everyone relies on<br />

something called the Chart, a table that lists the relative value <strong>of</strong> picks. Mike<br />

McCoy, a minority owner <strong>of</strong> the Dallas Cowboys who was an engineer by<br />

training, originally estimated the Chart. <strong>The</strong> coach at the time, Jimmy Johnson,<br />

had asked him for help in deciding how to value potential trades, and McCoy<br />

eyeballed the historical trade data and came up with the Chart. Although the<br />

Chart was originally proprietary information only known by the Cowboys,<br />

eventually it spread around the league, and now everyone uses it. Figure 19<br />

shows how highly the chart values first-round picks.<br />
