One team is the only undefeated squad left in the NFL. The other has a future Hall of Fame quarterback and a winning record but also some questions this season.

Given that buildup, perhaps it shouldn't be so surprising to see the opening Las Vegas spread on the Rams (Team A) vs. Packers (Team B) game slated for Sunday in Los Angeles.

But this is at least interesting: If the opening line of the Rams being favored by 8.5 points holds throughout the week, it will mean Green Bay is the biggest underdog it has been with Aaron Rodgers at quarterback.

Counting playoff games, Rodgers has started 164 games for the Packers in his career. The most an opponent was favored by as of now came in the playoffs following the 2014 season, when the Packers and Rodgers were eight-point underdogs at Seattle for the NFC title game. (The Packers were on the verge of winning that game, you might recall, before Seattle rallied late thanks to an on-side kick and won in overtime. Green Bay did, however, cover the spread).

The Rams, who already defeated the Vikings this season, are 7-0 and have been favored by at least 6.5 points in every game this year.
