Little League 6 last years ages 5-7 and 11-12. 8th grade hoops for 22 years and freshman boys hoops for 3 years.
I have 12 and 8 year old boys and only coached them their 1st year. I may help out now but want them to experience other personalities. They have been lucky to be with very good coaches.
Its really simple if you state your rules in a parent/kids meeting before the season starts at how things are going to be so they have nothing to come back at you with. Homework, grades, practice, priority. No practice, no play. Grades fall, no play. Only excuses for missing practice is family emergency, homework, or vacation. Works well for me. Oops, or sick.
