the kid's coach and athletic director both deny that Sandusky was ever there. The AP says Sandusky was at a camp for Polynesian players in the spring, which Ah Ching attended, and encouraged all the kids at the camp to attend PSU, but that seems to be the extent of their contact:
It should be noted that we can find no information that Ah Ching was being recruited, heavily or otherwise, by Penn State other than recruiting letters, with that information coming from the player himself. It should be further noted that there is no credible evidence whatsoever that any contact Sandusky may have had with Ah Ching came under the direction of the Nittany Lions football program.
Sandusky wrapping himself in the Penn State name, though, would not exactly qualify as a shocking development given his emeritus status at the university since leaving the football program in an an official capacity in the late nineties.

I'm not saying it's impossible, but I think we have to balance what Ah Ching says with the denials from his coach and AD.
