As a minority owner and vice-president of the Dallas Cowboys in the National Football League (NFL), he was credited with inventing the trade-value draft chart.
[1][2] In 1981, he and a business partner, future Dallas Cowboys owner Jerry Jones, co-founded Arkoma Production Company, which was active in gas-rich areas such as northwest Arkansas and was able to profit from more than 500 of some 2000 wells they had drilled.
[5] When Jones bought the Dallas Cowboys in February 1989, McCoy became a minority owner with a 5% stake in the NFL franchise.
[9] With the success of the Cowboys during the 1990s and the departure of key personnel such as Dave Wannstedt and Norv Turner,[10] the trade-value draft chart gained prominence in the NFL and every team now employs a version of it.
[13] Five years after formulating it, McCoy left the Cowboys to return to the oil and gas industry.
