Disagree, the marginal revenue exceeds the marginal pay of another 3, 5 or 7 rookie contract guys or vet. min players. Let's take one additional game at Gillette --- 68,000 seats at an average ticket price of $115 --- assume a sell-out, and that produces marginal revenue of $7.8 million. 7 10 years in the league vet min guys with no signing bonus are paid $850,00 apiece, for total expanded salary costs of $6 million dollars. This excludes any additional parking, food or beer revenue. It also excludes any additional TV revenue.
This is a bit of an extreme analysis, as the Pats have the most expensive tickets, but I am also giving the Pats the most expensive JAGS for the example. More likely, the additional gate revenue produces five to six million for the owners while they shell out 2.5 to 3.5 million for the bottom of the roster.
