This is how I did it when I was coaching a 3rd and 4th grade team.... We were undermanned to start the season, so we practiced defense/Defense/Defense and used our defense to set up fast breaks on offense... The league that I coached in allowed Full Court Pressing unless you were up 10 points...We did that until the score was usually 10 to 0 and then put the press on if the opponent ever got within 10 points. The benefit is that a full court press or a half court trap will lead to turnovers by the other team and lead to fast break opportunities for your team and also eliminate having to run your half court offense on many trips down the floor. The year we did that we started out 0-2, but finished 8-2 and average over 50 points a game in 3rd and 4th grade league, when other teams sturggled to break 25 a game. I also had another experience with a girls team that I coached on the same grade level and I had absolutely nobody on the team that could dribble the ball when the year started...The emphasis on defense in practice actually helps the offensive skills as the players get better when making the defensive players work in practice. But in the Girls league, no zones, no traps, no junk defenses, so we had to run half court offenses...so we had five basic plays that were run out of a the same set....(I had tried to run a motion offense, but had no luck, because of the lack of skills) By having the players know exactly where to go on each play, it helped keep the guards from dribbling themselves into trouble as the plays were designed to pass the ball and did not involve dribbling other than to get the ball up the court. Overall, the best advice I can give is put in a full court press if allowed, half court trap if allowed...or if only man to man is allowed, use a Run and Jump defense that is a man to man defense where a man jumps the dribble and everyone rotates to a different man.....Getting easy offensive chances will help your team win games and get them confidence to run the offensive sets when you are in a half court set.
