A fluke win would be more like something quirky happening in the game resulting in a close victory that shouldn't of happened Getting destroyed for 60:00 in every phase of the game shouldn't be seen as a fluke but if that is how you want to see it then I guess that works.
Let's not get into this eagles discussion again. They completely dismantled the steelers last week. End of story.
My point isn't anything about the Eagles; it's that it was a fluke for the Steelers to play as badly as they did last week. The Steelers looking impressive does in fact make last week a "fluke" in a logical sense, I'm just purely arguing semantics here. Same way I'd call today's Patriots performance a fluke.
