Last week I was pretty confident that I would be able to answer this question after watching the game. Unfortunately, I saw a team that was capable of winning lose. I did not see a team that was still missing assignments and so they lost. I did not see a team that was getting man-handled by superior talent and so lost. I saw a team that showed that they were the better team but still lost.
I have no idea how you project winning from a team like this. If it doesn't win the games in which it's performing better than the other team, how can you be confident that they'll win any games? Poll fail for setting the minimum at 6. I was more optimistic after ND 2015. In that game, I knew that we had fixable problems (I was wrong that we'd fix them).
Tennessee is not the best offense we will face. They are certainly not the best D we will face. We need to decide that this can't happen again.
