This will be the fourth time the Packers are a seven-point underdog with Rodgers under center. According to ESPN's Rob Demovsky, he has lost all three of his previous games where this was the case:
The Packers are a 7.5-point underdog in the NFC title game, only the fourth time in Aaron Rodgers’ 191 career starts (including playoffs) he’s been at least a touchdown underdog. He lost the other three (but did cover): 2018 at the Rams (7.5), 2015 Divisional round at Arizona (7) and 2014 NFC Championship at Seattle (8.5).
It is safe to say that these have been some difficult matchups for Rodgers. Unfortunately, this may be his tallest task yet with San Francisco having home-field advantage.
The 49ers managed to make quite the statement the first time around with a 37-8 at Levi's Stadium in Week 12. Although it would be unwise to assume that will have any impact this time, it should still be noted that the circumstances in which they are very similar.
Regardless, the prospect of the Packers being such a huge underdog with a quarterback of Rodgers' caliber in the mix should b taken with a grain of salt. After all, he did manage to cover the spread in each of the games. While it does not mean much to him, it certainly will for plenty of bettors over the weekend.
