My opinion on this is that NJ located sports teams face certain challenges in terms of fan support that may not exist in other places.
NJ is a Professional sports dominated area with at least 15 Professional Sports Teams/Venues within ~2 hours of most NJ Residents all competing for fan attention (Giants, Jets, Eagles, Yankees, Mets, Phillies, Knicks, Nets, Sixers, Rangers, Devils, Islanders, Flyers, Red Bulls, NYCFC). IMO most fans in this area have a professional mindset which does not include the donations and giving part which is necessary for competing in sustainable way as a college program.
NY & Philly Media are not really interested nor vetted in propagating or covering Rutgers sports at a high level unless we are winning significantly. NJ Media is can be either overly negative or non-existent.
Rutgers does not have the historical anchor or success in Football that other programs such as Nebraska can draw on family or traditional support
Higher Income families in NJ - who might bring forth a more substantial donor base - do not typically view Rutgers as the first choice when it comes to college options for their children.
Crowd attendance at games (in general) is becoming more challenging for any team or program given better viewing technology and accessibility at home, less interest from younger generations and higher costs for tickets/parking/concessions etc.
We're kind of in a Catch 22. Need to win to draw interest.......but also need to draw interest to help build a winning atmosphere.
