I agree that it's not time to jump ship. But when your defense only gives up 15 points while creating two turnovers and spending most of the game on the field because the offense isn't moving the ball at all, then your defense has done its job.
They did their job. The long play to get Philly in position was absolutely a fluke. With the party in the league, you're gonna win some and lose some of those. Just how it is. I'm not remotely worried yet.
