Excellent work.
My comments:
On the revenue side, I don't see the cash the Reds got in trades.
On the expenses side, I think you need the player payroll charge common to all teams and the benefits calculations mentioned by Jax.
I also think that the "administative" expense must be off by a factor of at least two and perhaps way more. You are talking about salaries for the entire front office and scouting staffs, the Reds' share of the entire minor league organization, transportation, medical expenses, lawyers, lobbyists and probably a dozen more things I cannot think of at the moment.
