If you're on a basketball team, the major positions have specific rules and roles that govern each job. To improve your skills, it's a good idea to learn the specifics of each position and learn what place you might fill on the court.  Centers are the big players who guard the hoop. The center is usually the tallest and most physical player on the court, whose job revolves around grabbing rebounds, posting up near the hoop for easy tip-in shots, and guarding the hoop on defense. Famous centers include Kareem Abdul-Jabbar, Shaquille O'Neal, and Yao Ming.  Forwards are the second-biggest players on the court, physical enough to play defense and go down low, but dexterous enough to shoot from the outside. Good forwards make excellent cuts and are powerful physical presences in the arc. Famous forwards include Charles Barkley, Bill Russell, Tim Duncan, and LeBron James.  Guards are the architects of the offense. The guards are the players that carry the ball down court, set up plays, and shoot from the outside. The guards typically score the most points and are valued for quickness, accurate passing, and sniper-like shooting. Great Guards include Michael Jordan, Kobe Bryant, and Magic Johnson. . If you want to be a better basketball player, practice your fundamentals. Good dribbling, shooting, and defensive skills are the best way to spend time becoming a good player. Don't practice making behind-the-back passes, or lowering the hoop so you can practice your 360 dunks until you can shoot lay-ups from both hands, 10 times out of 10, and you can make 20 free throws in a row. . Good basketball teams can keep the ball moving at all times, keeping the defense off balance and on their heels. When your team has the ball, keep your passes quick and crisp to move the ball around and find an open lane to the hoop. It's a common misconception that basketball needs to be played by virtuosic ballers who all dunk non-stop and hog the ball. Good players pass, selfish players dribble around constantly and lose the ball. Practice your passes. . One of the most unheralded basketball skills is the rebound. Because lots of shots miss, the ball will end up somewhere unpredictable, bouncing off in one direction or another, sometimes straight up in the air. When the ball goes wild, both teams have a chance for getting control of it, meaning that the ability to out-jump your opponents and grab it is very valuable. When you practice shooting, practice running up on the hoop to grab your own rebound, if possible. If you play down low, as a forward or a center, practice "boxing out" the other players with your backside, muscling them away from the prime real-estate. Get low and stay wide, keep your arms out, and keep your eyes on the ball to give yourself the best chance of grabbing the board. . As you learn to work as a team, you'll eventually want to start working out plays and formations, most of which involve some kind of pick and roll. Setting a pick means using your body as a barrier, for one of your teammates to run a defender up against. Most of the time, forwards will set picks for guards, though any player may set a pick on offense. When your teammate has the ball, you need to move around. Don't just stand there flat-footed waiting for a pass! Make cuts under the hoop, Try to shake your defender, and get open. Give your team supporting options by moving around and staying fluid. Find open space and look for the open shot.
