I dont get the PoV that the writer made the whole thing up or got misled. He's a writer for the Ames newspaper. This article is basically career suicide for him as far as Iowa State athletics go. Obviously before he ran this article he verified/cross referenced his sources and his editor did the same thing. So to say he made the whole thing up is pretty far fetched.
As far as Fred speaking out...why would Fred confirm anything in the article at this point? What point would there be for him to do that? Fred just left a place he's loved and signed a $25,000,000 deal with the Bulls and is now in the NBA. Why the hell would he suddenly come back and say "yeah I hated our AD, he treated us like crap and was super cheap". Nobody would ever do that.
Maybe the writer got misled by multiple sources...thats certainly possible...but to say that "OMG FRED DEBUNKED IT" or "THE WRITER MADE THE WHOLE THING UP" is completely asinine by cyclone fans.
edit: Also, why did Pollard deny multiple requests for comment in relation to this article, but then suddenly go on a twitter/news cycle splurge after it was published?
Remember, usually the most obvious answer is the correct one.
