As a season ticket holder, I havn't seen this letter yet.
So they recognize that the $$$ given to the AD is a "statement" of a meaningful role that we would like to play when determining the success of their programs.
Sounds to me like they may also be saying, You don't donate enough $$$ to have a say in all of this, so we'll make the decisions for you.
As for "Their Expectations" I see this as an attempt to gloss over what they have already failed to accomplish with the football program.
Seating & Parking contributions? WTF? Didn't realize my purchase of season football tickets and parking were now considerd to be in the form of a contribution.
