LWS is right.
If you go to church, you put some money in the offering plate. You ask the preacher or priest how much they and each of their staff are making beforehand?
If you donate to St Jude's, you ask how much each doctor, nurse and administrator makes before you do?
We all give to causes. Some charitable, some hobbies (like football), some professional. The average person probably contributes to a half dozen causes each year. And that's before we even get into all the other services and goods you pay for.
Do you really ask all those people how much they're making before you contribute? How often they get paid? How the money is disbursed?
I get it, that you want your contribution to be used effectively, and efficiently, and even wisely. Makes sense.
So you'll be very pleased to hear this: at 90% throughput to the athletes, Spyre is already at the top end of that general kind of organization (75% to 85% is the usual, and widely accepted legitimate range).*
That should be all you need to know; getting into the salaries of each member of the staff is a bit overboard.
Go Vols!
* An organization called Charity Watch, which grades charities on how efficient they are with donations, sets 75% as the gold standard. Any charity that is able to push 75% or more of the funding it receives through to the targeted beneficiaries is considered "highly efficient." Spyre is not a charity, but its business model kind of works in the same way, and so the comparison seems apt.
