The MASN contract stipulates that they receive the same RIGHTS FEES, not the same equity payments. The O's, in their deal to "allow" the Nats to come to Washington, gave themselves like 90% of the equity payments, while giving only 10% to the Nats. This rises by 1% per year until the Nats cap out at 33%. The money given to both clubs every year is a combination of the rights fees and the equity payments.
Thus, as I said, the Nats would prefer more of the money get loaded into the RIGHTS FEES that they share equally, and the O's would prefer more of the money get loaded into the EQUITY PAYMENTS they get far more of.
But in no way has the money that's been going to both clubs been equal, It's been something like $30-40 million higher going to the O's every year.
