What fun!
Lot's of good tips above.
I'd just say that as a ball handler he really ought to practice ball type drills a lot (a lot) if he's new to the game. For example:
On the court/driveway
- Up the court with the right hand. (w/o looking at the ball)
- Down the court with the left hand. (eye's up again to see who is open, what the defense is up to)
- Switching the dribble from hand to hand, dribbling backwards. (keeping the ball safe)
- Sprinting with the dribble, between the legs and/or zig-zaging with the dribble. (ball security)
- Just plain sprinting. Make sure he runs on his toes and not flat footed.
At home/in front of TV
- Pass the ball to himself between hands. (eye's off the ball)
- Work the ball around the body, between the legs around the head, whatever...
*Just generally get a feel for the weight and feel of the ball. It's for hand eye coordination, muscle memory and just good excercise. It looks like a circus act and isn't a "game skill" per se but it works. It helps with confidence and ball control and can be practiced almost anywhere or anytime.
Oh, and
have fun!
