You are describing a quid pro quo (trading sex playing time) not a victim situation.
Could it also be a case of trading sex for a full scholarship at LA Tech? What would be the value? $25-30k/year? The problem with that scenario is that Tyler wasn't paying her with his money. He was using the university's money for his personal benefit. Was the university a victim in this case?
Another scenario could be the added playing time she was getting in exchange for sex. If she was getting extra playing time for sex, it meant fewer minutes for all the other players who weren't sleeping with him. Were those young ladies victims of his relationship as well?
A lot of people (and the university) were affected negatively by Tyler's behavior, including his mother. But mostly I feel for the young lady involved because Tyler should have known better. And yes, I place full blame for the Monica Lewinsky scandal on Bill Clinton, not the impressionable young intern.
