I know several other "G5" universities with the same issue at least according to their fans. Just in the past couple of years looking on their message boards prior to playing them. Ohio and Miami-OH -> Ohio State. EMU -> Michigan and MSU.
Even in the belt they deal with this and talk about it on the Belt board. Southern Miss -> Ole Miss and Moo State. Georgia Southern and Georgia State -> UGA and Georgia Tech. TXST -> all those other "P5" Texas schools. SOAL and Troy -> Auburn and Bama, etc.
Believe me, students and alum identifying with universities other than the ones they attend is not a UL specific problem.
