Shots from the corners behind the arc are taken more often than any other three-point attempt. The reason is a piece of court geometry rather than a change in shooting technique.
The arc is not a true semicircle
The three-point line is drawn as an arc from the basket but is cut off by straight segments running parallel to the sidelines. Those segments create the corners.
Without the cut-offs, the arc would extend beyond the sideline near the baseline. The straight sections exist because the court is not wide enough for a full circle.
The consequence is that a corner shot is taken from noticeably closer to the basket than one from the top of the arc, while scoring identically.
Why distance matters so much to accuracy
Shooting accuracy declines with distance because the required launch speed rises and the margin for angular error narrows. Small differences in range produce measurable differences in conversion.
A shot worth three points from a shorter distance therefore carries a higher expected value than the same shot from further out. The advantage is arithmetic.
Because the difference persists across every player, the corner is valuable to specialists and stars alike. It is a property of the court, not of the shooter.
How offences created corner opportunities
Driving towards the basket forces help defenders to collapse inward, which leaves the perimeter momentarily unguarded. A pass out to the corner exploits that rotation.
Teams therefore station shooters in both corners and space the remaining players to widen the driving lane. The alignment is designed to generate that specific pass.
Because the corner is the furthest point from the basket that a help defender must cover, the recovery distance is longest. Openings there last marginally longer.
The costs of standing in the corner
A player in the corner is out of rebounding position and contributes little to offensive activity until the ball arrives. The role demands patience.
The corner is also a confined area, with the sideline and baseline restricting movement. A defender can trap a player there with fewer helpers.
Passes into the corner travel across the defence and are vulnerable to interception. The reward comes with a turnover risk.
How defences responded
Defensive schemes now prioritise closing corner shooters over protecting the paint in some situations. The choice is an explicit trade of shot quality.
Some teams deliberately concede longer perimeter shots while denying the corner. Defending by location rather than by player has become standard.
The result is a spatial contest over a small area of floor. Both sides are optimising against the same geometry.
