I think he is a big part of it but I agree- JMD and BB deserve some blame.
IIRC from Matt Light's commentary on the debacle, it wasn't the snap count/cadence that Stork f-ed up, it was tipping when the snap was coming and Googs not detecting that as an issue.
In such a loud place, clearly they used the head-bob to non-verbally disseminate when the snap was coming.
The other part of the problem is they never changed the interval of the silent count.
Maybe Googs coached it right but Stork was too much of a dummy. He did it fine in 2014 but with Connolly and Wendy on either side of him it wasn't an issue as fmr centers they handled the communication, protections, etc.
I think Googs getting canned was also due to the young players not improving. Might have been cultural too. Seems like Scar and Josh work great together and I never heard anything from Josh on Googs. I dunna know...
