The defense did what they were supposed to do. They let a touchdown go at the end of the game, but then again, McFadden shouldn't have ran out of bounds for one, and the offense should have taken as much time off the clock as possible. It's sort of like the game we won against the Giants the first game in. Sure, they could have blamed their defense, but they put the blame on Eli for throwing the ball out of bounds and stopping the clock for us.
I don't know why the onus is on the defense to play 4 quarters of shutout ball and generate all of these turnovers, but the offense can slide by kicking field goals all day. If you want a shut out defense, you're going to have to invest more resources into that side of the ball, which I'm not opposed to.
I'm perfectly fine with Jalen Ramsey or Bosa to really shore up that side of the ball, because Marinelli is getting a lot out of that side of the ball with no names at a lot of the positions.
