I think a major problem for SC fans is, and has been for a very long time, an unwarranted sense of superiority that is in no way backed up by history. WBB is very strong now, but that is a recent phenomena and when Dawn leaves, WBB will go back to being another middle of the pack in the SEC team. Baseball, probably the most successful major sport, has had flashes of success, but it is, and has never been any sort of long term dynasty. Winning back to back CWS probably created a totally unrealistic expectation for the future of Baseball. MBB, for the most part, is mediocre to bad historically, with a few bright spots thrown in. Football, especially football, is the poster child for mediocrity and always has been, yet football fans seem to have the attitude that gamecock football is some sort of traditional powerhouse and every season is going to be "special".
Every P4 school "wants it" in every sport. Some, like UK, focus their "want" on MBB. They enjoy a successful football team, but they don't obsess over it, same with baseball. MSSt, for years, was a baseball powerhouse. They are not anymore but they still see themselves as a baseball power. They are reasonable about football. They are passionate fans, but they don't delude themselves into thinking they are going to challenge for the SEC championship every year.
I think the "sense of destiny" that drives SC fans is a complete delusion. There is nothing in gamecock sports history to support any sort of sense of destiny. That delusion, and seeing Clemson enjoy the success they have recently enjoyed, pushes some SC fans to the brink of mental illness.
