Yes, certain schools ARE Bluebloods. Looking at wbb:
UConn is the bluest blood (royal blue) of them all. Southern Cal, Tennessee and Notre Dame Stanford, Baylor are all blue (though some are faded). South Carolina's blood is getting bluer by the year. Even LaTech retains some blue tinge. UConn is royalty. The rest are aristocrats. I have never heard anyone debate that UConn is NOT a blueblood. Occasional someone will argue that the are not THE only blueblood.
I really don't understand your post especially the bolded part. Every fan base feels slighted when not worshiped. "ESPN hates us!"
(with all that said, I felt the human committee members and pollsters were just plain stupid this year. They looked too much at who was injured rather than who was playing for y'all. The computers had it right.
