Think of it this way: if Vikings had played at Philadelphia after week 3, Philadelphia would have been favored by 3. Since then, the following has happened:
- Vikings played a middling Giants team at home and blew them out.
- Philadelphia played a couple of middling teams on the road (Detroit, Washington) and lost two tight contests.
- Diggs got hurt.
- Lane Johnson got suspended.
Now Minnesota is favored by 3. Are the above events sufficient to swing the line 6 full points?
