If memory serves, I think this interesting tidbit was included in the Alumni BOT report.
I may be wrong, but I seem to recall this pre-dating of the talking points ahead of the press conference goes with the fact that there was a Freeh group internal memo in April or May saying that they had not uncovered anything that would point to a cover-up at all, let alone a football-based cover-up, and speculated that maybe if there was a cover-up, it was to protect the institution, not the football program. Saying it was perhaps an institutional thing could then easily get pointed back to the OGBOT for having heard about it and doing nothing. The close ties that many on the OGBOT had to The Second Mile would then be exposed, as that aspect had been effectively buried since Nov. 2011.
And that is why it is supposed that the OGBOT insisted on no further investigation or claims vs. TSM in the settlements. They knew the real problem was with TSM, not PSU, and while they could distance themselves from the football program (Joe ran everything, we are just innocent pawns ala Blazing Saddles' Mongo), they could not really yammer their way out of both the PSU and TSM ties. Curley going to Raykovitz of TSM (mandated CSA reporter) and being told there was nothing to see here would have carried the weight it always should have. People would have realized that the incident was reported, and that it was not on PSU for fumbling the protocol ball. PSU did what they thought was right given the information McQ gave them.
As Curley said later, I wish we had asked more questions. In his defense, I believe they did not know what they did not know, and certainly not after twice being told by experts that there was nothing to the incidents reported.
