I'm not saying I necessarily disagree with your takes on 4 and 6. I was simply saying it is more effective to drive those principles home in practice where you can control more of the variables. You can drill, you can pause, you can try different things, all at a pace and in a setting that is more conducive to those lessons sinking in.

Yelling something from the stands, while still being supportive, during a game isn't going to be as effective as a practice setting. As many have stated, depending on how it's done, it might even be counterproductive.
