It's an interesting question. I listened to Dunne on the Schopp and Bulldog show this afternoon and it sounded very targeted (I won't say biased but that's probably the closest word).
He said all the people quoted had positive comments about Sean but even more positive about Beane and even said that Beane probably put out more fires than most people know about because of Sean.
Made references to Allen being the best thing since sliced bread and Sean was always going to hold him back. (paraphrasing).
I honestly do think that the digging and info that came out wasn't true and all happened but at the same time, I also believe that Dunne has an axe to grind with McD since he doesn't give "new media" media credentials.
