That's why he's shell shocked. Happens to good to great qbs. I've seen it happen with Brady after a few truly hard hits. He will not be anywhere the calm and collected he has been. But then when he's got protection he's back on game. This is what happened to Everett before he ended up with the Saints or Warner at the end of his Ram career and with the Giants (both teams had horrific O lines). It came back for him with Az because he had a much better O line. Bottom line-it can come back for Goff-if in fact he IS shell shocked.
