It is estimated that UW will lose 20K season ticket holders, and most of the premium boxes/seats.
Luxury boxes cost $20K/year, plus the price of tickets.
Season tickets cost $500, plus mandatory "donation" of $400 (2016 figures, my last year).
Do the math, and don't forget to add parking, concessions, merchandise, and voluntary donations (I stopped mine).
Bottom line is that it will be more expensive to keep him than to fire him.
