Rumor I heard was that Shoop's wife had a "break" with PSU. That she was going to leave with or without Shoop.
I can't go into details about the allegations of what happened with/to his wife..but I suspect (if that rumor is true) that Shoop will blame PSU and it is his position that he should not have to reimburse PSU for salary already paid.
I also heard that his wife had little interest in living in Pennsylvania. She was very happy at Vanderbilt, but that feeling didn't continue once the family moved to State College. For the record, I have also heard Mrs. Franklin is not in love with State College and certainly does not make a lot of attempts at public showings and the like. Not to say she should be obligated to, but she does not share Sue Paterno's commitment to the school/community. Who knows though, just a rumor a heard, i take it with a grain of salt.
