Do the Nats receive revenue sharing like the other "poor" teams (like the Marlins)?
I don't know, but
NatsAddict can probably answer that. He posted an elaborate explanation in
Off Topic/Red Loft a few years ago about why the Marlins have the lowest payroll. I don't think it has anything to do with TV/radio rights. I recall that teams with the lowest attendance receive revenue sharing, at the expense of those with higher attendance. MLB does not require the team to use that money to build a better team, in order to attract more attendance. NatsAddict's conclusion was that Marlins owner Jeffrey Loria (the former Expos owner) simply enriches himself by pocketing the revenue sharing, (if I recall what he wrote correctly.) And that he can make more money with a low payroll/low attendance team, win or lose, than he could by trying to field a winner.
