"That rush" has been garbage this year. They're ranked 20th through four games in sacks, just not the same group tbh. Now we can say they had a slow start or whatever, but the Rams have been pretty good in pressures and sacks allowed and Goff's moving well in the pocket so this is a tough game for Seattle to "get right" in.
The historical stats I've seen trumped out there of late need to be disregarded. The Rams are a different team. The Shehawks still have an elite secondary, but their rush has not looked good.
Goff on third and long I agree is a concern, however for different reasons. I have enormous respect for that secondary and even if Jared's got time it's going to be dangerous as a matchup.
