Ralph Lee Sampson, Jr. (born July 7, 1960) is an American retired basketball player. A 7-foot-4 phenom, three-time College Player of the Year, and first selection in the 1983 NBA draft, Sampson brought heavy expectations with him to the National Basketball Association (NBA). The NBA Rookie of the Year, Sampson averaged 20.7 points and 10.9 rebounds for his first three seasons with the Houston Rockets before injuries began to take their toll. Three knee surgeries later he retired as a four-time All-Star, an NBA Rookie of the Year, and an NBA All-Star Game MVP (1985) under his belt. One of his many career highlights was a buzzer-beating shot to dethrone the Los Angeles Lakers as Western Conference champions in 1986, derailing their hopes for coveted back-to-back NBA titles, and sending the Rockets to their second NBA Finals in the team's history.

Sampson was already 6 ft 7 in (2.01 m) tall by the ninth grade, reaching 7-foot-1 in high school in Harrisonburg, Virginia. He averaged nearly 30 points, 19 rebounds, and 7 blocked shots as a senior (after averaging 14 points and 11 rebounds as a sophomore, and 19 points and 17 rebounds as a junior), at Harrisonburg High, leading the team to state AA basketball championships in 1978 and 1979. His senior year he lost the high school player of the year award to another talented center, Sam Bowie. However, he did get a form of revenge against Bowie, outplaying him in the Capital Classic, getting 23 points and 21 rebounds with 4 blocks in a game styled "Battle of the Giants".
