I don't think expecting 9 win seasons is unreasonable as a fan. Especially considering there's a good 4-5 guaranteed wins built into our schedule every year (1-2 directional schools prior to SEC, Vandy, Kentucky, One more directional school before the clowns.
No one was calling for Spurrier or Meyer's head when they won 9 games. The loudest screams from the fan base came during the years we were floundering under Zook and Chump. And to be frank, we're no different than any other fan base. Take any university that has "tradition" (e.g. OSU, Michigan, 'Bama, ND, USC, 'Bama, UT, etc.) and you'll find that they aren't tolerant of losing either. SOS just happened to bring us up to the level of "traditional" standards very quickly, setting our expectations in line with other big schools.
