I disagree with you. Dranov (essentially) contradicts McQuery
MM wants people to believe he witnessed (i.e., heard) sexual assault in progress. Dranov states that he did not believe whatever he was told required immediate police notification. Those two actions and points of view are diametrically opposed to one another.
If Dranov were told that an explicit sexual assault involving an under-age youth was witnessed, then that deserved an immediate call to some "authority". That authority could have been Police, CYS/DPW, PSU HR... someone. Neither Dranov nor McQ Sr saw that as a necessity. Hence, the logical interpretation is that the information MM relayed was not definitive and conclusive. Instead it was vague and nondescript. (Edit: Dranov and McQ felt comfortable with waiting until the next day for MM to tell anyone else what occurred. That is more evidence that MM did not witness what he now wants people to beleive)
MM further wants folks to believe that he told everyone to whom he spoke that he witnessed Sandusky assaulting a child. The actions of everyone in the chain suggests that MM did not communicate that he witnessed what he now wants people to believe. He clearly did not witness anything close to what was in the GJ Presentment.
The assumption, here, is that Dranov, McQ Sr, Paterno, Curley, Schultz, Mrs McQ, MM girfriend, Courtnet, etc are all reasonable people and the chances/likelihood of those 5+ people being the only 5+ people on the face of the planet who would not react to hearing evidence of a child being molested are, well, infinitely worse odds than winning the Powerball.
