I think you're ignoring the donations the school and seat licenses the school gets from playing in Hartford. They essentially get to double dip.
I suspect we'll never see the true data, but id love to see a donation breakdown between Gampel and Civic Center season ticket holders.
Now with all this said, I tend to agree it's not a good deal, but the worse part is how UConn accounts for it all. As
@CL82 noted a lot of these expenses are just paper not cash out and something of the things the AD takes the expense for are kind of dubious as well.
The on campus stadium and deficit are such big talking points, that could pretty easily be resolved with a) 'committee' to investigate an on campus stadium, b) figure out a better way to spread the expenses out aside from parking it in the AD which makes the school like inept.
