Find your opponents weakness

It's as simple as this...If the dribbler likes to go right, make him go left. If the opponent likes to go left, make him go right( this is a good reason for a ball handler to practice dribbling with both hands).

Do not flop...(unless you are great at it)

Trying to take a false charge will give you a bad reputation with the referees. If you get caught you wont be a refs favorite. Only flop when it looks natural...cheap but that is sometimes what the game is about. Think of the San Antonio Spurs for example, I haven't seen them play a fair game in my life yet they still win.

Foul....if you have to

If a guy thats a little too big for you has a wide open layup, foul him quickly. It is easier to make a layup than a free throw. This is a personal favorite tip.

Dont settle for a jumpshot

Driving in is one of the most important parts of the game. You get easier shot which means more points(unless you cant make a layup).

Find your Strenghts

If you are great at one particular thing, exploit it. If you are a great shooter, keep shooting and getting better. You cant only get better through practice.

Basketball is a non contact sport

Basketball does not encouraging contact, that is what football is for. Do not play too aggresively or you might start a fight. People don't want to have some one harrassing them while there trying to have fun. This is a good tip to save you from a trip to the hospital.

Play within your game

No one likes a player that hogs the ball when hes not good at it. If your good at defense focus on putting a lot of dedication to it. If your a great shooter, settle for a jump shot. If your good at getting to the rim, focus on that. You don't have to be a superstar!!! just show that you can contribute.
