I'm having a hard time thinking of College MBB games considered a big rivalry on a national level, besides Duke/NC.It’s fun within the state...with no register outside...the very definition of a small rivalry...fun though it may be to the two fan bases...
Ky & Louie might be another, but don't think that's played up on a national level
Most are local in state rivalries that occasionally spill out nationally.
Nothing bad about the Rutgers /Seton Hall one being the same
