Leonard Robert Rosenbluth was an American professional basketball player in the National Basketball Association (NBA), but he is remembered, first and foremost, for his college basketball player days. He played college basketball for the North Carolina Tar Heels, where he was Helms Foundation Player of the Year (1957), consensus first-team All-American (1957), second-team All-American – AP, UPI, INS (1956), third-team All-American – NEA, Collier's (1956), ACC Player of the Year (1957), and 3× first-team All-ACC (1955–1957).

The North Carolina Tar Heels Men's basketball program is a college basketball team of the University of North Carolina at Chapel Hill. The Tar Heels have won six NCAA championships in addition to a 1924 Helms Athletic Foundation title (retroactive). North Carolina has won a record 133 NCAA tournament matchups while advancing to 31 Sweet Sixteen berths, a record 21 Final Fours, and 12 title games. It is the only school to have an active streak of reaching the National Championship game for nine straight decades and at least two Final Fours for six straight decades, all while averaging more wins per season played (20.7) than any other program in college basketball. In 2012, ESPN ranked North Carolina No. 1 on its list of the 50 most successful programs of the past fifty years.
