Like I said Bob, there's a difference between unsold and sold but empty. Those seats are almost all sold. Visit the ticket website and you see that they are unavailable for purchase. Don't ask me why people shell out that kind of money and then don't bother to attend the game.
Of 960 $50 seats, 694 are sold to season ticket holders - 72%. There are over 800 of the $23 seats available for games (on average) so that's where the focus needs to be. If none of the $50 seats sold you would have a case. They are selling.
Maybe they changed the number of $50 seats? I agree with Bob F I've looked at times and there are tons of $50 seats available. Also, the university probably gives away a fair number of the seats too so they can count them as 'sold.' The whole thing is a joke and needs to be rectified. It's embarrassing to watch a game on tv and see tons of empty seats, especially against another HEA team.
I agree with TerrierFan that they should market more to kids. Also, what are they doing to market to young alumni? Would be interesting to know how many kids who have graduated in the last 10 years have bought season tickets.
