Daddy ball sucks unless coaches DD's are dudes! As we all know, that's usually not the case. We left a team years ago with 3 Daddy's, a Mommy and another daddy that kept the book. Coaches kids would miss practice/tournaments, show up late etc. because of other sports. However, other kids were asked to give up their other sports to be committed to the team. This was U11 where kids are still figuring things out. My DD was also asked to just hit clean up and not play the field since daddy's DD played her position. The writing was on the wall...we bounced.
I have no problem with a parent coach, as long as said parent A.) knows the game and in it for the right reasons. B.) is realistic with their DD. I've coached, my kids, in all sports, but by 10, 11, 12, it's time for them to play for someone else. And this is coming from a 20 yr high school and college head coach.
