This is unfortunate, but this 1000% falls on the University and the Athletics Marketing Dept. They should have been doing something about this for the last 2-3 months to get the alums involved. It should not come down to a group of people on a message board and players begging for people to come to the games.
As I have said in the past this goes much deeper. The majority of SHU alums just do not have the love for the school because the school did nothing to develop that love while they were students. Luckily this has changed in the past 5 years or so, but a ton of alums from say 95-10 look at SHU negatively.
This is a fantastic point. As a young alum who watched the core 4 and IW during my time as a student, theres no reason for me not to go. However if the team was a horror show while I was a student I would have minimal interest.
