Background: Richard Francis Dennis Barry III (born March 28, 1944) is an American retired professional basketball player who played in both the American Basketball Association (ABA) and National Basketball Association (NBA). Named one of the 50 Greatest Players in history by the NBA in 1996, Barry is the only player to lead the National Collegiate Athletic Association (NCAA), ABA and NBA in scoring for an individual season. He was known for his unorthodox but effective underhand free throw shooting technique, and at the time of his retirement in 1980, his .900 free throw percentage ranked first in NBA history. In 1987, Barry was inducted into the Naismith Memorial Basketball Hall of Fame.
Context: After the 1966-67 season, Barry became one of the first NBA players to jump to the American Basketball Association when he signed with the Oakland Oaks. In the ABA's first season, the Oaks were the only ABA team located in the same market as an NBA team (the Warriors). The Warriors went to court and prevented Barry from playing for the Oaks during the 1967-68 season. Barry instead worked on Oaks radio broadcasts during the ABA's first season.  During the 1968-69 season Barry suited up for the Oaks and averaged 34 points per game. He also led the ABA in free throw percentage for the season (a feat he repeated in the 1970-71 and 1971-72 seasons). However, on December 27, 1968, late in a game against the New York Nets, Barry and Kenny Wilburn collided and Barry tore ligaments in his knee. He tried to play again in January but only aggravated the injury and sat out the rest of the season, only appearing in 35 games as a result. Despite the injury Barry was named to the ABA All-Star team. The Oaks finished with a record of 60-18, winning the Western Division by 14 games over the second place New Orleans Buccaneers. In the 1969 ABA Playoffs the Oaks defeated the Denver Rockets in a seven-game series and then defeated New Orleans in the Western Division finals. In the finals the Oaks defeated the Indiana Pacers 4 games to 1 to win the 1969 ABA Championship.  The Oaks' on-court success had not translated into solid attendance. The team averaged 2,800 fans per game. Instead of remaining in Oakland for another season to see if the championship would draw fans, the team was sold by owner Pat Boone and relocated to Washington, D.C. for the 1969-70 season.
Question: How many teams did he play for
Answer: 

Problem: Background: John Winston Ono Lennon  (9 October 1940 - 8 December 1980) was an English singer, songwriter, and peace activist who co-founded the Beatles, the most commercially successful band in the history of popular music. He and fellow member Paul McCartney formed a much-celebrated songwriting partnership. Along with George Harrison and Ringo Starr, the group would ascend to world-wide fame during the 1960s.
Context: During his marriage to Cynthia, Lennon's first son Julian was born at the same time that his commitments with the Beatles were intensifying at the height of Beatlemania. Lennon was touring with the Beatles when Julian was born on 8 April 1963. Julian's birth, like his mother Cynthia's marriage to Lennon, was kept secret because Epstein was convinced that public knowledge of such things would threaten the Beatles' commercial success. Julian recalled that as a small child in Weybridge some four years later, "I was trundled home from school and came walking up with one of my watercolour paintings. It was just a bunch of stars and this blonde girl I knew at school. And Dad said, 'What's this?' I said, 'It's Lucy in the sky with diamonds.'" Lennon used it as the title of a Beatles song, and though it was later reported to have been derived from the initials LSD, Lennon insisted, "It's not an acid song." McCartney corroborated Lennon's explanation that Julian innocently came up with the name. Lennon was distant from Julian, who felt closer to McCartney than to his father. During a car journey to visit Cynthia and Julian during Lennon's divorce, McCartney composed a song, "Hey Jules", to comfort him. It would evolve into the Beatles song "Hey Jude". Lennon later said, "That's his best song. It started off as a song about my son Julian ... he turned it into 'Hey Jude'. I always thought it was about me and Yoko but he said it wasn't."  Lennon's relationship with Julian was already strained, and after Lennon and Ono moved to Manhattan in 1971, Julian would not see his father again until 1973. With Pang's encouragement, arrangements were made for Julian (and his mother) to visit Lennon in Los Angeles, where they went to Disneyland. Julian started to see his father regularly, and Lennon gave him a drumming part on a Walls and Bridges track. He bought Julian a Gibson Les Paul guitar and other instruments, and encouraged his interest in music by demonstrating guitar chord techniques. Julian recalls that he and his father "got on a great deal better" during the time he spent in New York: "We had a lot of fun, laughed a lot and had a great time in general."  In a Playboy interview with David Sheff shortly before his death, Lennon said, "Sean was a planned child, and therein lies the difference. I don't love Julian any less as a child. He's still my son, whether he came from a bottle of whiskey or because they didn't have pills in those days. He's here, he belongs to me, and he always will." He said he was trying to re-establish a connection with the then 17-year-old, and confidently predicted, "Julian and I will have a relationship in the future." After his death it was revealed that he had left Julian very little in his will.
