Ravens are NFL's biggest favorite this week

The Baltimore Ravens are favored by 14 points over the struggling Jacksonville Jaguars. That's the largest point spread of the week, and it marks the largest of the season for the Ravens.

The Ravens' history as a double-digit favorite is a strong one. The Ravens are 28-0 straight-up when they're favored by 10 points or more, according to RJ Bell of Pregame.com.

Since 2000, all NFL teams are 399-67-1 straight-up when favored by double digits. That's a .856 winning percentage.

The only time a double-digit favorite lost this season was Week 9, when the San Francisco 49ers were upset by the St. Louis Rams.

Ravens coach John Harbaugh was asked if it was going to be a challenge to motivate his team going against the last-place Jaguars (2-11).

"There are probably two kinds of people when it comes to preparing for a football team -- that's those that look at the record, and those that look at the tape. And those that look at the tape recognize the challenge that's in store for us," Harbaugh said. "So, we're going to have to be at our very best to win any game in this league, and that is especially true in December and especially true against a very young, highly-motivated football team that plays extremely hard and has a lot of young talent."
