One player that comes to mind when I think of Goff is Brees. Brees wasn't mobile and wasn't known for his canon of an arm. The Saints ran the ball a lot more than you would think and did it with a two back approach like the Lions. Brees was good at throws over the middle like Goff and the Saints would also pick up those chunk throws over the middle like the Lions. Nothing really comes to mind that wows me about Drew Brees. I do think Brees though had a little better accuracy than Goff, but given the Campbell connections, it seems they are trying to make Goff into a poor man's Drew Brees.
