I thought it was BS analysis. For those who don't recall, whoever the talking head was during the broadcast said that when Williams was looking around examining the D pre snap that was a obvious tell that it was a pass.
Every back on every team is looking around at where the defenders are on every play no matter if it's run or pass.
If it's a run, they dont just blindly slam into the called hole. They know the play design and the defenders positions pre snap will determine how the play unfolds. Ok, maybe Brent Fullwood just slammed into the hole.
If it's a pass, same thing.
It was complete BS.
