A throw in, also known as an inbound pass, is a method of putting the ball into play in a basketball game. During a throw in, the referee gives the ball to an offensive player who is standing out of bounds either on the sidelines or baselines. The referee blows his whistle and the ball becomes live. Then, the player taking the throw in has five seconds to pass the ball to a teammate who is inbounds or the ball will be turned-over to the other team.
There are rules that dictate how players take throw ins. Here are the rules of throw ins in basketball:
Throw ins will always happen on a spot around the boundary lines either on the sidelines or baselines. Most throw ins have to occur in a specific spot, but some allow the player to run along the baseline to find the best angle and positioning.
There are three general places that the throw in will take place:
In youth basketball and some college games, alternating possession is used to determine which team gets the ball and how the ball is put into play. With alternate possession, throw ins are used rather than jump balls. An alternate-possession arrow device shows which team starts with the ball and changes once the ball is thrown into play.
Here are the types of throw-ins in basketball:
After a shot is made, the throw in takes place on the baseline where the point(s) were scored. The other team gets the ball and has five seconds to make the throw in.
On a baseline throw in, you can move along the entire baseline and even pass the ball to a teammate behind the baseline for them to throw in. However, you still only have five seconds to make the throw in.
A throw-in will be considered illegal if the player does not follow the rules that dictate throw-ins. For example, if a player takes longer than 5 seconds to throw the ball into bounds, the throw-in will be declared illegal and the ball will be turned over. Also, if the player steps into the bounds of the court before letting go of the ball on the throw-in, their throw will be considered illegal.
On throw ins, there is a great opportunity for the opposing team to steal the ball. Defending players will guard close to boundary lines to prevent the thrower from making the inbound pass. Typically, a player will stand directly in front of the in-bounding player to try to catch the ball and obtain an easy steal.
Another defensive strategy is trapping. On a trap, defensive players will trap the player who catches the throw-in in the corner of the court or near the boundary lines.
Throw-ins happen on several occasions during basketball games. First, they will happen anytime the ball gets knocked out of bounds. The player to last touch the ball before it goes out of bounds loses possession, and the other team will get the throw-in. Throw-ins will also occur after a basket has been scored; the team that gave up the basket will get a throw-in from the baseline to start play again. Lastly, throw-ins will happen when certain fouls occur.
