turnover

hi to all coaches...
i have a problem with 15 and16 years old players..they are not so much gifted...and we have BIG problem with turnovers..we lose ball in bad passing and bad dribling, but not much in traveling.. game average 28....what is the best drills to minimize number of turnovers? i tried with passing drills, but not much help....
thank you.. coach Darko

You might try putting an extra player on defense in practice ( we did that a lot ) and tell them NO bad passes, take a 5 second count first.

You also might try what we called the "man maker" drill.... 3 on 3 NO dribbling.
3 offensive players on the baseline and 3 defensive players at the free throw line... offense must get the ball over half court without dribbling the ball.... split the half court into thirds and the offensive players must stay in their lanes.

There is no 10 second or 5 second violation.... they just have to keep working until they get the ball over half court without turning it over.
