As I read, I can see the reasoning behind both sides of the story. HOWEVER, my my dd's coach came up to me, says hey, I want to see the report card, I'm fine with that, as long as the 1st report card is a baseline for what is expected. Remember, I'm looking at a player who wants to go to college to play softball there as well. My youngest wants to go to college to play ball, as well as being a teacher. My oldest doesn't, so I can truly look at both sides.
For example, dd has a 3.4 on her first report card. That is the baseline. Second report card, she now has a 3.3, is that worth a benching no, she is still a B student. If it is a 2.8, maybe less game time. Why? Because maybe as a parent, I'm putting more emphasis on her pitching then I am on grades. What is wrong with a coach holding me accountable since my dd wants to go to college as a softball player? Remember, for the 2nd report card it is like January, so what if you miss action during a winter tournament. Maybe it isn't big brother looking at you, but a coach who cares about the development of your dd into college player IF she wants that route. For a travel player who doesn't want to go that route, then who cares if she has a 1.72 GPA. For my oldest; if a coach asks her for her report card, I'll let him know that this is fun for her so let her be. That's my job to worry about her grades.
buckncm- I check my dd's grades the same amount as you do. I see a missed assignment, it is 1 less practice at home for pitching for my youngest. If my older, at least a weeks extension before she can think about her license.
Please remember, I'm looking at both sides, as a parent who has a dd wanting to go to college, and another who wants to go but not for softball, but music (yet she's a great RF, decent catcher, and runs like lightning). So I see both sides of the story.
