You're not understanding what I'm saying. Of course everyone knows defenses switch and disguise their look up to the snap.
I'm saying that after the coach mic is cut off, Goff was more susceptible to mistakes because the defense would shift and mcvay couldn't tell him what he wanted him to do.
My analogy is that sometimes at the 15 second cut-off, when the stadium lights go off for goff, he's in trouble. With Stafford the lights go off at 15 seconds but he has a big ol flashlight on top of his helmet.
Now you could say coaches talk to their qb between plays but the mistake has already been made, and it doesn't mean they fixed the problem.
The Miami game last year is a great example. They played the same fronts that the bears and the pats played against him in the SB and he till couldn't make the proper adjustments. On one of the 2 fumbles returned for a td, he did not make the protection adjustment and the DE came untouched.
