Tough to say how the offense might have done with longer fields, for sure struggled more because that's obvious. But the defense gave them short fields and the offense turned those into touchdowns. Not much more you can expect.
I'm on the JR bandwagon and can live with the occasional mishap because of the upside of some very good throws.
Oops - I just remembered it was 2 bad throws. But only one of them really was very bad.
