Sort of. I'd look at it this way
Flagship State U > Next Tier "State U" > City focused or directional state U
Every single school you mentioned takes a backseat to the primary state U in its state. They all do. K State is far below KU in fan following, Pudue to Indiana, Pitt to Penn State (and Temple even more so), ISU to Iowa, Ok State to OU, NC St. to UNC...all of them. There aren't any exceptions that I know of (CA situation is odd with Berkeley and UCLA both flagships, they split CA north/south). FSU and Clemson, as strong as they are, are still less popular than UF and USCe.
Many of those schools are grandfathered in, but each of them are limited compared to the potential of the flagships. So in looking at who to add, a conference should weigh that. Cinci, Houston, Memphis, UCF and USF are much more limited in potential appeal than UConn. Their ceiling is inherently lower.
