Offense overall was night and day compared to last week. Where last week it looked like it was the first time most of these players ever took the field together, this week it looked like they've all been playing together in this offense for a long time.
Goff was excellent.
Kupp looks like a savvy vet.
O-line played well.
I think my favorite moment was when McVay called a time out from the sideline just as Goff was seeing what he had against the Raiders defense, and he apparently liked what he had, and he got was visibly a little miffed at McVay for calling the time out. It's little things like that sometimes that can indicate that a QB is getting in and in command out on the field.
Next week is the dress rehearsal, however, and will be a more meaningful test.
