When coaching young or first time players, it is important to approach the game from a simple, basic plot and then add the frills and skills as the players progress. Think in terms of the basic advantages listed below, evaluate your players and then take logical actions to get the most from their strengths. You must work on weaknesses in practice, but choose a game plan that will allow your players to feel successful. To develop the game plan, look at the court as your battleground, game board or whatever analogy you prefer. Think about the basic advantages your players possess.
Common sense goes a long way.
There is no way to make your players taller. Because tall people are closer to the basket than short people, it is easier for them to reach rebounds. Its easier for tall people to shoot over short people. Tall teams tend to intimidate small teams - a basic human survival reaction that attributes superiority to the larger opponent. All other things being equal, the taller team will likely win most of the time, proportional to the disparity in height.
