What Is Top Of The Key In Basketball?
The top of the key in basketball is a location on the court that refers to the top most point on the arched line just above the key.
Size of the Key
The basketball court has gone through numerous changes throughout the sport's history. There have been several sizing and dimension changes to the height and radius of the key and its semicircle. The first iteration of the key was much larger than what it looks like today.
There is still no standard for how large the key should be, with it varying in different leagues (NBA, NCAA, and FIBA). In the NBA, the key is 16 feet wide and 19 feet from the baseline to the free throw line. The semi-circle at the top of the key has a radius of 6 feet. For NCAA, the key is 12 feet wide and also 19 feet from the baseline to the free throw line. The semi-circle at the top of the key for NCAA is also 6 feet.
Top of the Key Strategy
In the modern game, players have chosen not to make as many shot attempts from the top of the key. The reason for this change is because shots from the top of the key are the most inefficient for players to take. Out of all two-pointer attempts it is the furthest spot away from the basket. Three pointers are only slightly further away from the basket and are worth three points instead of two.
Shots from the top of the key yield about 86 points per 100 possessions. That is far below the number for corner three pointers (119 points per 100 possessions). Due to that difference being uncovered teams have had their players take less shots from the top of the key in today's game.
However that does not mean it is irrelevant in the modern sport. It still is useful for setting up plays and providing a location that players can reference when spacing themselves out on the court.
