Yes, I have coached a lot of youth basketball. Most important things to teach are fundamentals. For your age range I would teach and hit the following:
Box out drills
defensive turning the ball drills (no hands, behind back)
dribbling (both hands) very important, I usually use the shell drill for this
Bigs, catch ball, drop step, finish off the glass, switch sides, learn to use both hands.
Layups, layups, layups, layups, free throws, layups
Theres plenty more.
Urban Meyer: We're going to rotate them right away. We don't redshirt here at Ohio State. We're changing that up. We're going to have the culture out here that there's no redshirting. If you don't play here, it's because you're not good enough. It's not because we're holding you back. We're going to recruit the kind of player where we want them on the field right now. That's the approach we took at Florida, and it's the approach we're going to take here.
