Goff had his reads spoon-fed to him by his head coach. The Pats defense was so dominant against Goff in part because they changed the defensive look once Goff's radio turned off. They literally had 2 plays on defense before the snap - the fake play to show when the radio was on, and the real play when the radio was off.
That's not a trick you can use on Brady because he makes his own reads and checks out of plays at the line. So your logic is deeply stupid there. In Goff's situation he would see the defense change the play and just check into something else, which Goff is unable to do mentally.
Like, part of why Goff got sacked so much by a Pats pass rush that didn't do much most of the year was because he couldn't change the protection calls once the radio turned off and the Pats D shifted. It's not just a personnel thing, it's Goff's mental deficiencies at work.
