While I am sure that there are some schools that don't like/hate us, I believe the talk about all of the schools hating us is waaaaaay overblown. There are a lot of top flight universities that play us in many different sports, that don't have to schedule us at all. You would think that if they don't really like us, they wouldn't play us and take a chance on losing.
That is just my opinion, which is just as valid as any one else, because no one can prove it either way. The indications, that we can measure, ie. how many schedule us, doesn't support tons of haters. But hey, I am just an old guy and not an expert all on things LU.
