All three of these articles do little to bolster your case.
Yes, Modrak was forced out of Philly when Andy Reid got the power over personnel. Big deal. His replacement, Heckert, didn't even have final say in personnel, even though he was the GM. Andy Reid is one of, if not the most powerful head coaches in the league, so it's no surprise that Modrak was fired in that soap opera.
In the PFT archive, it never even hints that Modrak used reporters to plant stories. It quotes one of Florio's unnamed sources that he's being considered for top FO posts because Lenny P and Tom Donahoe keep plugging him. Also, look at the tone of the article. It's clear that Florio has issues with ESPN that extend way beyond Tom Modrak.
Lastly, the Jauron saving Modrak's job is a 1-liner in 1 media outlet, again PFT with one of their "league sources". Did the Bill's beat reporters ever mention this story? You'd think if it was real, it'd be documented by a named source, more than once. Sorry, doesn't pass the smell test...
