This is crazy on so many levels:
One person (Mike McQueary) said that another person (Tom Bradley) once told him Greg Schiano said he saw something happen with Sandusky. Bradley says that Schiano never came to him with anything like that and that he never said this to McQueary. Schiano says he never told anything like that to Bradley. Schiano loses Tennessee job (and potentially millions of dollars and the biggest head coaching job he's had a shot at) as a result.
It's hearsay of hearsay, is inadmissible in court, and never lead to any pursuit of Bradley or Schiano by authorities in Pennsylvania who went after everyone they could reasonably get when this situation went down.
Tennessee AD looks like supreme idiot right now - but everyone saying Schiano can't be hired (multiple Tennessee ranking state officials are saying this) because of his connection to the Sandusky case are basically throwing out every standing tenet of our justice system. He should sue the shit of them if he can.
