First off, I am an employee of Steubenville City Schools, although I will not say who I am or what my role is. I'm sure I can get into a lot of trouble for posting here..
There is a lot of talk between employees about the Bill Rhinaman and Old Lenny connection. One of the prevalent hypotheses among co-workers is that Mike McVey ordered Rhinaman to destroy all records and data concerning the multiple rapes by the members of the football team. Bill may have resisted but did as ordered in the end in order to keep his job with the district and his retirement.
As payback for forcing him to do something extremely illegal, Bill may have adopted the "Old Lenny" moniker and leaked some of the vital information that McVey was trying to cover up. I don't know if this is the case or not, but it seems feasible. No one really thinks that Bill did what he did without any direction from above.
Additionally, there is chatter that Mike McVey was also forced by his "superiors" to cover-up the rapes by the football team. As to whom those superiors are, your guess is as good as mine.
