if you want to mathematically figure on overs do this
add up both teams scores points for and against then divide by total number of games played by both teams see if it matches up with posted total according to spread EX:
Broncos vs Cowboys broncos scored 179 allowed 91 cowboys scored 104 allowed 85
= 459 points divide by 8 games played = 57.375 or 57 1/2 total now we looks at posted total 56 1/2 hmmmmm right there spread is broncos - 7 1/2
Both defenses Bad vs Pass Cowboys ranked 27th Broncos ranked 30th vs teams that are all sub .500
Denver has lost key defenders Champ bailey and Elvis dumerville gone !
Giving up over 3 td's a game and hundreds of yards to all terrible teams; i mean bottom feeders this year except Ravens who won 2 games at home !
