You’ll lose the kids attention during transitions.
Unfortunately most youth coaches realize they’ll spend more time babysitting and less time coaching unless they keep the kids interest.
Planning your practices in advance helps a lot but even those few minutes it takes for you to set up those pup-goals or put out the markers is enough for your team to go nutso.
If they’re in place and you say can say.. each of you now take one of those positions…you’ll save yourself a load of exasperation.
