Dikembe Mutombo

Dikembe Mutombo Mpolondo Mukamba Jean-Jacques Wamutombo (born June 25, 1966), commonly referred to as Dikembe Mutombo, is a Congolese American retired professional basketball player who played 18 seasons in the National Basketball Association (NBA). Outside basketball, he has become known for his humanitarian work.

The 7 ft 2 in (2.18 m), 260-pound (120 kg; 19 st) center, who began his career with the Georgetown Hoyas, is commonly regarded as one of the greatest shot blockers and defensive players of all time, winning the NBA Defensive Player of the Year Award four times; he was also an eight-time All-Star. On January 10, 2007, he surpassed Kareem Abdul-Jabbar as the second most prolific shot blocker in NBA history, behind only Hakeem Olajuwon. He averaged a double-double for most of his career, and is 12th all-time in career double-doubles, and tied for second all-time in career triple doubles involving points, rebounds and blocks.

At the conclusion of the 2009 NBA playoffs, Mutombo announced his retirement.

Michael Jordan

Michael Jeffrey Jordan (born February 17, 1963), also known by his initials, MJ, is an American former professional basketball player. He is also a businessman, and principal owner and chairman of the Charlotte Hornets. Jordan played 15 seasons in the National Basketball Association (NBA) for the Chicago Bulls and Washington Wizards. His biography on the NBA website states: "By acclamation, Michael Jordan is the greatest basketball player of all time." Jordan was one of the most effectively marketed athletes of his generation and was considered instrumental in popularizing the NBA around the world in the 1980s and 1990s.

After a three-season stint playing for coach Dean Smith at the University of North Carolina, where he was a member of the Tar Heels' national championship team in 1982, Jordan joined the NBA's Chicago Bulls in 1984. He quickly emerged as a league star, entertaining crowds with his prolific scoring. His leaping ability, illustrated by performing slam dunks from the free throw line in slam dunk contests, earned him the nicknames "Air Jordan" and "His Airness". He also gained a reputation for being one of the best defensive players in basketball. In 1991, he won his first NBA championship with the Bulls, and followed that achievement with titles in 1992 and 1993, securing a "three-peat". Although Jordan abruptly retired from basketball before the beginning of the 1993–94 NBA season to pursue a career in baseball, he returned to the Bulls in March 1995 and led them to three additional championships in 1996, 1997, and 1998, as well as an NBA-record 72 regular-season wins in the 1995–96 NBA season. Jordan retired for a second time in January 1999, but returned for two more NBA seasons from 2001 to 2003 as a member of the Wizards.
