I am reminded of this great scene from
Good Will Hunting.
(Warning: explicit language. F-bomb thrown around quite a bit.)

If this team can't get behind the OP's daughter, and rally for her, they aren't very good friends.
If a team was playing together and they realized one member had what it takes to go for Olympic gold, would they really sit around and say, "Oh, no, you have to stay here with us. We can't make it, but you're part of our team, we need to stay together, no matter what"?
There is also this quote from Marianne Williamson's book,
A Return to Love:
(This quote is NOT Nelson Mandella's, as was incorrectly attributed to him for a long time.)
“Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. It is our light, not our darkness that most frightens us. We ask ourselves, Who am I to be brilliant, gorgeous, talented, fabulous? Actually, who are you not to be? You are a child of God. Your playing small does not serve the world. There is nothing enlightened about shrinking so that other people won't feel insecure around you. We are all meant to shine, as children do. We were born to make manifest the glory of God that is within us. It's not just in some of us; it's in everyone. And as we let our own light shine, we unconsciously give other people permission to do the same. As we are liberated from our own fear, our presence automatically liberates others.”
"We are all meant to shine, as children do." But, not the OP's child? She has to stay small, so as not to upset the coach or the team?
Maybe the problem isn't the leaving, (although the OP & DD haven't made the choice yet.) But how to leave
gracefully?
