Honestly, who really cares? Whether he did or not doesn't change my opinion of PM. Everyone has a different opinion of Schiano and his personality and involvement at Penn St. Just because someone's opinion of him differs from yours, why does that have to destroy your opinion of PM?
As far as supporting the Haslams, you make it sound like he is not capable of independent thought or making his own decisions or way in this world. I highly doubt he needs the Haslams to accomplish anything he wants to. To suggest anything other is absurd. He could make one phone call to any number of teams and be a GM if that is what he wanted. Pretty sure the Browns just hired one and it wasn't PM. How does that fit with your narrative.
For the record, I was against Schiano but I'm not going to lose sleep or waste mental energy on who supported whom. I'm all in with CJP and am moving forward.
