There's this thing called Confirmation Bias. When a person has formed an opinion (EJ will never win, Coach has to get canned) they will attach themselves to evidence that supports their opinion and ignore or excuse evidence that doesn't.
So, when the Bills commit a costly fumble, it's a sign of bad coaching and a lack of preparation. When the OTHER team commits a costly fumble, it's dumb luck. Think about the third party unbiased observer - would they construe Aaron Williams' strip as anything short of a highlight reel play?
Now, it goes the other way too. You'll notice plenty of posters who've pretty much forgotten the Bucs game and how EJ looked like a rank amateur.
