What exactly am I trying to play off as fact?
We don’t know what changes, if any, he was making at the line. He could have made right changes, could have been wrong changes, or maybe he wasn’t making any changes at all but just wanted to see how the defense would react. I’m just not going to assume he was doing the right thing just as I’m not assuming it was wrong.
The only thing we know is that whatever they were doing wasn’t working very much.
