I'm going to dip my toe into this water...
Final Four goals are great, but unrealistic at this point.
At least make the tournament (Goal #1). Every year that our name is not called on Selection Sunday is another step into mediocrity. To make the tournament pretty much spells out your season that you were able to win the games you should have and you were competitve enough compared to top talent. I am not saying this is all easy (especially with NIL, portal, and roster changes), but it is more obtainable and should be the fast track to setting a consistency or culture. To make the tournament 1 out of every 5 years is not going to cut it.
At least make the first/second round every year and then let's look at setting new goals. I think you could repair this fanbase and bring back the enthusiasm that was lost. At least this is what i'm starving for.
