The former first overall pick in the 1987 NBA Draft, David Robinson dominated the paint in the '90s. With a combination of size and agility "The Admiral" took home Rookie of the Year honors in '90, was crowned Defensive Player of the Year in '92, and even took home the scoring title in '94. While it's certainly badass enough to retire from the game as a champion, it's even more badass to announce your retirement before the season begins, as Robinson did before the start of the '02-'03 season. Did we mention David Robinson is also the most recent player to score a quadruple-double in a game? That's right, 34 points, 10 rebounds, 10 assists, 10 blocked shots in 43 minutes. Boom.
