you seem like you really want to know so i'm going to give you an answer but i cannot list all of the reasons for obvioius reasons. Numbters are a big reason and Buffalo owns the best qbr against figure in the leauge ..... most teams with a number in that category will prove to be the best in the leauge. The other is buffalo is 2nd in opponent yards per carry. The Bills own the better qb. Public perception is a factor and theyve had all the preseason love. The number is set to attract money to both sides... now you have some basics, i will tell you the biggest square reasons to like a side is by what you saw most recently and if team B just killed team C and team C killed team A then surely team B will kill team A. You dont need to worry about the line at all. Injuries are already in the number.
