Whenever looking at the schedule and predicting outcomes I look at the opponent QBs first. Rating Qbs as +, =, or - .
Let's skip the division games as those are more complicated due to familiarity. So, in non division games we have:
3 Plus Qbs--Prescott, Wentz, and Brady
3 Minus Qbs--Allen, Jones, and Haskins
3 Avg (=) Qbs--Foles, Tua, Stidham
Out of those nine, I think one could say we have the better QB in 6/9 games. So, say we win 5 of those nine just based on QB ability. If we split the division we go 8-8. 6-10 is probably a 5% chance, worst case scenario(unless Goff gets hurt) while best case is 12-4 and the most frequent outcome likely 10-6 from looking at QB vs QB with some divisional knowledge thrown in.
