Hmmm...if a coach can't get 100% from the kids, the problem is the coach. Captains aren't going to fix that.There hasnt been a single practice ive been to the past few years where some kids play at 100% from start to finish,Some do, some dont.players will make it to the following season.
Getting 100% is not difficult. A coach has know the game and how to teach the game to children. (Part of teaching children is to know how to give correction without berating.) Kids want to play well...if a coach is giving them the tools to play better, the kids will work harder.
There is a video of @RADcatcher doing personal coaching. Coaches should study that video. She is doing drills that are boring and repetitive...and the kid doesn't even notice. RAD and the kid are having fun. The kid would have done those drills all night with RAD if she had gotten the chance.
As to the captains....the problem was that the OP was picking "one girl" to be captain for the entire season.
