You actually said:
Except... All the times they've gotten off the field.
They held Ol Miss' high scoring offense to 7 points in the second half. That was a lot of getting off the field.
I'll agree that I'll feel more confident with more depth, and better 3rd down efficiency that would likely come with that, but your "narrative" about your personal confidence levels is a bit ridiculous in this day and age of offensive-slanted rules and high scoring offenses, consiering what they have to work with roster-wise. This Dhas FAR outperformed any expectation for te he year, so far.
If you want to watch 3-2, punt on third down games, you'll need to hit the archives.
