re: Three more women have come forward in an amended Title IX lawsuit against LSU (O included)

Because Paterno, on record, knew about the abuse that took place and only reported it to his "superiors".

There is no proof that Orgeron knew of anything. There is one statement made by the former boyfriend of one plaintiff, that the defendant (Orgeron) has already publicly denied.

They are entirely different situations.

ETA: and there was already an independent investigation that cleared Orgeron of any wrongdoing.
