Free throw

Free throws can normally be shot at a high percentage by good players. In the NBA, most players make 70--80% of their attempts. The league's best shooters (such as Steve Nash, Rick Barry, Ray Allen, José Calderón, Stephen Curry, Reggie Miller, Kevin Durant, and Dirk Nowitzki) can make roughly 90% of their attempts over a season, while notoriously poor shooters (e.g. Dwight Howard, DeAndre Jordan, Wilt Chamberlain, Andre Drummond, Andris Biedrins, Chris Dudley, Ben Wallace, Shaquille O'Neal, and Dennis Rodman) may struggle to make 50% of them. During a foul shot, a player's foot must be completely behind the foul line. If a player lines up with part of his or her foot on the line, a violation is called and the shot does not count. Foul shots are worth one point.
