The above link goes into GB for failure with Q4 comebacks and I noticed as well when trailing by 7+ pts at anytime in the game. I've read elsewhere that the book sometimes won't offer a line, near the end of game, so you may not be able to bet against GB at start of Q4. You'll just need to take a chance on the nearly 70% chance of winning and take their opponent.
There are also other interesting facts in the above article to follow, let's call it "since 2008"
•Since 2008 and including playoffs, Green Bay is No. 2 in average first quarter scoring margin (+2.33 points per game). Atlanta is No. 1 (+2.42 points per game).
•Green Bay ranks No. 2 in average halftime scoring margin (+5.39 points per game). New England is No. 1 (+5.62 points per game).
•Green Bay ranks No. 2 in average scoring margin through three quarters (+7.74 points per game). New England is No. 1 (+8.87 points per game).
•Since 2008 and including playoffs, the Packers have 25 wire-to-wire wins (games where they never trailed). Baltimore actually leads the league with 27. Five more teams have at least 20 such wins.
•Since 2008 and including playoffs, Green Bay is tied with Philadelphia and Pittsburgh for No. 2 in the league in games (41) where they scored first. Atlanta is No. 1 with 45.
•Green Bay’s 24-1 mark when leading by 10+ points at halftime matches that of Philadelphia for most such games in the league since 2008. Atlanta has the best record (22-0).
Here's something that maybe helpful for teasers (+6, +6.5, +7 pts) or at least SU:
"If Rodgers and the Packers don’t kick your ass, then they at least are going to give you all you can handle, as they are one of the most competitive teams in NFL history.
That is the way you need to look at it as a fan. When Green Bay’s not 6-20 in their failed comebacks and game-winning drives under Rodgers, they are 39-3 (.929) in the games he starts and finishes."
