The Packers have gone over the total in six straight road games. Green Bay has also scored at least 22 points in seven of their last nine games.
The 49ers led the NFL in yards per play overall and at home, second in the NFL, scoring 28.9 ppg. The 49ers have scored 30+ points nine times this season. With the extra preparation time, I expect the 49ers to light up the scoreboard again. I see this going over.
