Here is the lastest line I could find:
New England +4.5 -110 // Denver -4.5 -110
Over/Under: Over +55.0 -110 // Under +55.0 -110
So, it's really easy math:
N + D = 55
N = D - 4.5
D - 4.5 + D = 55
2D = 59.5
D = 29.75
N = 25.25
There you have it: Denver beats New England 29.75 to 25.25
I guess my 9th grade Algebra teacher was right, you will use it someday.
Den. 30
