The St. Louis Rams upset the previously undefeated Arizona Cardinals on the road last week, and they will look to do it again here in Green Bay on Sunday. The Packers are officially on upset alert, and they don't want to underestimate this dangerous opponent. An outright win is a big ask, but I'll take the points here with the Rams.

Here are my keys to the game:

1. Todd Gurley - After a quiet start to his NFL career, Todd Gurley had his coming out party in Arizona last week. The former Georgia Bulldog ran for 146 yards on 19 carries, helping the Rams win 24-22.

2. Pass Rush - Aaron Rodgers won't have much time to sit in the pocket this Sunday, as he goes up against one of the NFL's fiercest pass rushes. The Rams sacked Carson Palmer four times last week, and only the Denver Broncos have more sacks than St. Louis this year.

3. X-Factor - The Packers receiving corps has been hit hard by injuries, and the status of Randall Cobb and Davante Adams is in question for Sunday's game.

Selection: This is a play on the St. Louis Rams (8*)
