The Rams +134 points differential leads the NFL. In franchise history only the 1999 Rams had a better points differential through 9 games (+172).
Also worth noting, it's very rare for a team with +100 or better points differential at season's end not to make the playoffs. The last team to do so was the 2010 Chargers who were +119 but missed the playoffs at 9-7. It's only happened 4 times in the last 25 years (Chargers, 2008 Patriots, 2005 Chargers and 2004 Bills).
56 teams in NFL history have had a +130 or better points differential through 9 games. 49 (88%) made the playoffs. The last one not to make it was the 1975 Dolphins.
Only 9 Rams teams have finished a full season better than +134. All 9 made the playoffs.
Also, the Rams only need to average 14.9 ppg the rest of the season to end up with 400. Pretty crazy... Before the season I wrote that my hope was that McVay could help add 5.0 ppg and help them reach 300...
