American professional basketball players are the highest paid based on average salaries, with an average NBA player making $4.6 million in the 2014-2015 season. That can be attributed at least partially to the relatively small rosters of basketball teams.
Among American sports, Major League Baseball comes in second, with an average player salary of $4.17 million a year. The National Hockey League is third in the United States, with an average salary of $3.82 million, and the National Football League is fourth at $2.11 million.
Of the 17 highest-paying sports leagues in the world, nine are soccer leagues. India's Independent Premiere League is the second-highest paying sports league in the world. The English Premiere League and Germany's Bundesliga are fourth and sixth in the world respectively.
