To do what? Beat BC every other game or to win tourney games in March? Maybe schedule Colgate again? I don't know what the school specifically wants to do. Hopefully win games or be a top 25 team again? These aren't questions for the fans, they are for the school and the admin.
Syracuse fans will show up but the school hasn't been a great steward of money of late. Even for the last decade as the program declined, the fans have supported the team waaaay more than than other top-10 all time wins programs would have. You think UK would still be getting 20k fans through the door for a team that hadn't been to a tourney in 5 years? Or even relevant in the conference for a decade? Louisville built a huge new arena for basketball, hired a family coach who was awful and their attendance dropped by 50%. They're still struggling to get them back. As of last year, SU was 5th in the country in paid attendance and Louisville had dropped to 15th nearly 5k people per game fewer than a losing SU team.
