Because the league only awards one championship trophy to the winning club, championship rings are given as a valuable keepsake for the real players and team officials to keep to commemorate the triumph. In baseball, football and basketball, players usually receive a ring if they make it to their team's all-star game. In addition to the all-star game, players can be selected by their coaches for other all-star games such as home run contests or skills competitions. These events are often prelude to broader celebrations with their respective leagues. For example, in the MLB, all-star games are used as part of the qualifying process for the postseason. In the NHL, all-star games serve as preparation for the All-Star Challenge and All-Star Game. The winner of the challenge series is awarded the Stanley Cup. In the NBA, all-stars play in exhibitions designed to determine who will face off in playoff matchups. The winners of these games are awarded a prize called the Larry O'Brien Trophy. The Los Angeles Lakers have won the most titles with five. In soccer, players on all-star teams are recognized for their achievements with individual trophies. However, some clubs choose to honor their players by giving them engravable metal plates attached to a chain that is worn around the neck.
