Not to mention Flacco and the Ravens, who haven't put up 4,000 yds passing once since he took over, yet have been the model of success in the AFC.
Flacco's numbers(Team record)

2012

(8-8)
2014
27 TD 12 INT 3,986 yds
(10-6 Divisional playoffs)
I see the Ravens as more of the model the Rams can be, rather than Seattle. Strong defense/ST and a strong running game with a QB who isn't flashy, can manage the game, not make bad decisions but still make some big plays here and there, spreading it around, using play action and the deep ball.
BTW, Joe Flacco has now been in the league for 7 seasons and has not yet missed a single start.
