Against Green Bay, Garoppolo was 14 of 20 for 253 yards and 2 TDs (2 carries, 1 yard) in a 37-8 victory in the 2019 regular season. He was 6 of 8 for 77 yards and 0 TDs (4 carries, minus-1 yard) in a 37-20 playoff victory.
Dak Prescott was 27 of 44 for 463 yards, 2 TDs and 3 ints. (4 carries, 27 yards) in last year's 34-24 loss at Green Bay. He was 24 of 38 for 302 yards, 3 TDs and 1 int. (2 carries, 13 yards) in the 2016 34-31 playoff lose to the Packers.
I really wish fans would stop crediting QBs with W/L ratios and beating a team. Unless the rest of the team was on the sideline the entire time and the quarterback single-handedly whipped an opponent, he did not beat them, his team did possibly because the offense blocked better, the playmakers made more plays or the defense was better (or a combination of those things). The QB was just one factor.
Just in case someone wants to make the argument that if Dak hadn't thrown the interceptions against Green Bay, we would have won, the week before playing Green Bay in the playoffs, Garoppolo was 11 of 19 (58 percent) for 131 yards with 1 TD and 1 int. against Minnesota, and San Fran still won 27-10. Again, winning takes a team.
