I actually just made a post about the confidence I have in his playing confidence that could appear to fall in the categories you're talking about. However, I posted mine without reading any others posts expressing concern about his confidence. Included in that would be anyone attacking his personal mental health.

It's fair to question his playing confidence because of how poorly he played and how he is the face of the team last year that had the worst season since the 60's (50's?). There's plenty of reason to speculate based on what we've seen, or better yet didn't see, from him previously.

I want to see Tanner start and play the entire season, but I absolutely have concerns about his confidence as a QB and leader of the team.
