In the aftermath of a school shooting, a victim’s non-athletic father who has given up on life finds meaning in coaching his dead son’s basketball team to the championships.

I like that point about using basketball to distract them, but they really have to learn to deal with their loss.... it's a good midpoint.... I'll consider that for the Internal Goal part of the story....

Glad I could help. One thing I took from dpg's answer above is that ultimately winning or losing doesn't change the fact that life will go on. What will change their lives is if they can come together by sharing their grief and healing the community.

The notion that the school shooting's are usually caused by someone within the community who has become isolated and radicalised play's on the minds of the community and can lead to conflict and infighting. I'm not saying that is what happens in your story but it is an important point to consider as structurally there is no clear shadow or villain character, they are fighting against each other and the basketball team is the metaphor for the community unifying and fighting for a common goal.

Winning and losing matters but not as much as the community unifying in the wake of the tragedy. And while winning might expedite that unification, in this case it's not a make or break condition in my opinion.

Also, on the father and the players in the basketball team, it could be interesting how they deal with the tragedy as the stereotype is men tend to be insular in the grief. As a part of their arcs they could be using basketball to distract from their grief but learn that they need to face the problem head on and acknowledge their grief before they can truly unify and fulfill their potential as a team.

Again, it's hard to get all this into a logline but hopefully, it helps to clarify the concept for you.

I hear what you're saying about the third act reveal, but I disagree about the end of winning the championship. I see winning a championship as underdogs a great metaphor for overcoming everything if you work as a community, the exact lesson communities learn after a mass tragedy. In addition, each character on the team will start their arc as broken in some way from the shooting and through winning the tournament regain their dignity and past selves.
