From what I saw, it seems the Moore blame game really picked up because people were deflecting Kurt Warner's criticism of Dak. During his breakdowns, he pointed to a couple plays that he thought could be designed better. But he spent the majority of those breakdowns showing the bad reads, the late throws, and the missed windows.
I remember being surprised at all the criticism Moore was getting on those threads and even had to point out that every play he criticized for design issues resulted in a completed pass, some even for first down yardage. Nevermind his statements like, "I see Dak [throw into zone coverage] all the time," and literally stating multiple times that Dak is holding and patting the ball when he should have released it already.
But you can't criticize Dak without being called a hater or having one of his fanboys strawman what you said. Pointing to any failures on his part means you're, "blaming him for the loss," or some other type of deflection.
