Whether there's any truth to this extension story or not, I think the big takeaway lately is that Pioli doesn't seem like a guy who feels secure about his job.
The bullshit "off the record" type stuff that's been filtering out, which Babb and others have said Pioli constantly works at. His silence on the Winson thing, even though Romeo and Clark both spoke out, and even though it was a perfect chance to try winning some brownie points with the fans. It's far better for Pioli, especially with the banner and whatnot, for a narrative to spread about KC fans being unreasonable.
It's all setting up like part of his next sales pitch. And not even to Clark, because Clark would surely know how much of it was bullshit. It's geared for Pioli's next job interview with some other owner. "I knew Cassel wasn't that good, that's why I tried so hard for Manning. I regret following bad advice and not putting myself out there more. And those KC fans, boy, they just won't give a brother a chance."
And that's just in the last two weeks. There's plenty of time for more to be added to the list.
A guy who just got extended wouldn't need to cover his ass this way. He'd be sitting back with his feet on the desk, lighting his cigar with a $100. And if a guy who might have been extended in the last year, year-and-a-half is covering his ass like this, then he must not think the extension will save him.
Which would fit the equally-unverified twitter/radio rumors about "changes brewing" and Clark taking the bull by the horns and whatever else.
