You know why it seems like a lot of people don't care? It is because a lot of what you 'claim' above is just speculation. You have no idea what Galen's relationship is with Knight. The NCAA investigated Rupp and has still allowed him to run. As someone posted before, many collegians have traveled abroad on their own dime to compete unattached. As long as he is taking a full courseload, paying for his own travel, and training under the guidance of someone approved by the University's athletic department, I don't see how he's doing anything wrong.
I agree that the coaching situation seems kind of shady, but that does not just happen at Oregon--there are a lot of college kids who work out with post-collegians in separate sessions. It's commonly done in Boulder, San Francisco, and Madison, and I wouldn't be surprised to hear of it happening in more places.
I want to ask you though--what does the word 'legacy' mean to you? Do you think that Ohio State's football legacy has been ruined because some clown named Clarett lied to the cops, dropped out of school, and ruined his potential career?
U of O has accomplished so much as a program that whatever is happening with Rupp/Vin/Salazar is not going to ruin the legacy. Everything that Bowerman, Dellinger, Hayward, and even Martin built, and careers of athletes like Chapa, Divine, Moore, Pre, Wilkins, Davis, Salazar, and many others have built will not be diminished because of some suspicions that a few message board posters have.
