As long as the defense remains consistent, and the offense can at the very least take care of the ball. I think this team is very capable of winning all their upcoming games. As others have said, what did the Rams game in was the turnovers in the first half. If the hawks entered 6-6 into the second half, I think the game changes where instead of a 4th quarter destruction, it would be a second half destruction.
What also gives me faith is that this Seahawks offense also looked inconsistent going into the playoffs last year and we saw how that played out. I think what we gotta remember is that they are playing NFCW defenses in the final quarter of the regular season. Which means 2 things, the defense is going to look even better, and the offense is going to look worse. In the playoffs assuming it's not against the Cardinals. The offense is going to suddenly look better, and the defense is going to be giving up a few more plays than usual since they will be going against stronger offenses (Dallas, GB, Detroit come to mind and potentially the Patriots).
