A line that opened at a healthy 7.5-point advantage in the New England Patriots' way has already swung to a 10-point spread at some sports books early in the betting week for the AFC Championship Game.
The nearly double-digit spread at most books comes despite the Ravens' early season victory over the Patriots. That game came in Baltimore, but the Patriots are again facing a big spread to cover at home, which they were able to manage against the Houston Texans last weekend.
For comparison in this rematch of last year's AFC Championship Game, the Patriots opened last year's edition as seven-point favorites and eventually won the game by just three, 23-20. But despite the signs pointing to a close game in the cold New England night, many bettors apparently thought the early spread was too small, building the Patriots advantage in the early hours of the line.
The Patriots will be aiming to improve upon a 5-3-1 record all-time against the spread against Baltimore.
