There's an argument to be made that a team should always go for two, now that the PAT line has been moved back. There is little difference between the expected points per attempt between going for 1 or 2, so why not go for 2? Not sure I agree with it, but it's arguable.
There is absolutely no argument that the Bills were wrong yesterday. I've read through three pages of this and nothing can convince me that it was a mistake.
And it worked. And it's Monday now.
