Time has a funny way of working against the NBA big man. Kevin Garnett is learning that lesson the hard way.

Garnett is on the clock, and the persistent ticking that serves as the backdrop for his NBA career is fading to a whisper. Eleven games remain this regular season for Garnett to rest an ankle that is causing to him to play some of the worst basketball of his career. Garnett's ever-ticking clock is quickly leading to his 37th birthday in May. The pain in his ankle also serves as a reminder that, despite any minutes restriction Doc Rivers might place on him, the C’s starting center is defying a nearly infallible timeline for NBA big men each time he takes the floor.

Garnett has played in 1,320 regular-season NBA games and another 125 playoff games. He currently ranks 10th on the NBA’s all-time rebounding list with 13,820. Of the top 30 all-time rebounders in NBA history, only five -- Kareem Abdul-Jabbar, Moses Malone, Karl Malone, Robert Parrish and Kevin Willis -- played more regular-season games than Garnett. Each of those big men played beyond the age of 40, with Willis playing until he was 44, Parish 43, Abdul-Jabbar 42 and both Karl Malone and Moses Malone 40.

According to Garnett’s comments during NBA All-Star weekend, he has no intention of following in the footsteps of those players.

"When I'm 40 I want to be in the YMCA somewhere, busting a guy like you up, talking trash to you, killing your ego,” Garnett said. “Shooting the hook shot left and right, something I never do, and enjoying it.

Perhaps Moses Malone serves as the most apt comparison to Garnett in that both players entered the NBA directly out of high school, bypassing multiple years of 30- to 35-game seasons in college to play the NBA’s 82-game schedule. Malone's career ended after 1,329 games, nine more than Garnett has played as of today. When taking postseason games into account, Garnett actually has outdistanced Malone, with 125 playoff games to Malone's 94.
