I used to buy into this thinking a lot also, but not so much anymore. If our corners can't make a play on fade after fade after fade, we just won't win a game like this.
If we had somehow had a grinding drive towards the end of the second half, yes - maybe they have one touchdown less.
But our defense is atrocious right now and that's the story in this game. That and Dowdell's fumble in the red zone. I can buy an argument that it could maybe be 21-14 at half if a couple things went differently, but our defense is the overwhelming problem.
