The good news is that the things limiting our success offensively are all things which can be fixed. Given the youth and limitations in normal procedure with COVID, I don't expect the problems to completely disappear. I never played football, but I have competed at a high level (pool player, local tournaments and have competed against some pros). While it's not nearly the same thing, I recognize how much hinges upon the mental aspects of the game. The team has not established themselves and learned how to win and manage expectations. We have significant positive signals of mental grit, but putting things together consistently and making execution on the field an unconscious expectation are not yet established. Sadly there's no substitute for experience here. You take your lumps and you continue an intentional approach that makes execution of good decisions more likely and eventually you find yourself doing what you're supposed to automatically and no longer remembering why it was so much of a struggle to get there.
The hazard is indulging doubts. Abandoning good ideas that haven't connected yet. Trying to wing it. Yes you have to look at what happened and learn from it, but if the issue is you made an execution mistake on an otherwise good decision that is reasonable to expect you to execute in the future, you keep at it.
