Except Barron was NOT a "PSU official" during the November 2011 - May 2013 time period.
The Paterno lawsuit against the NCAA (and Penn State, as a nominal defendant) addresses issues during the November 2011 - May 2013 time period. What could Barron, a man with no association with either NCAA or Penn State during that time, have to do with the issues of that lawsuit?
Address that issue. That's the question that is being asked in the appeal to quash the subpoena. Address that issue, provide a substantive answer to that question. Thus far, you are not addressing that question, you are evading it.
