The two aren't mutually exclusive. Marshall can generate the cash needed by charging higher prices as they do for the better seats. People will pay that because they can afford it and see value in a better seat.
They can also attempt to build the fan base which is sorely needed by offering a standard $10 ticket for upper end zone seats. This appeals to young families , local HS students, church groups, etc.
While Marshall must keep an eye on the check book , no question; their main goal at this point should be building the fan base for the future. If they can't or won't do that, don't bitch about attendance when it continues to dwindle in a area where discretionary income is small and most can't or won't buy a $40 ticket.
It's a tough problem that only Marshall will be able to fix. Winning would certainly help.
