I suspect whoever voted for "$0 - They make their money when they sell the team." is not a Packers fan or has not actually thought about this very much. The Packers cannot be sold for profit, it's in the team charter that if the team is sold that all money goes to charity (I believe it was formerly a war memorial, but it was changed at some point). There is no rich owner to pay the bills when the Packers take a loss, they're only able to do that because they put their profits in a war chest/rainy day fund.

If you believe that the fair amount of profit for an NFL team is $0, then you believe that the Packers should not exist.
