Vince Carter used to defy the laws of gravity. These days, he’s defying the laws of aging. While most men of Carter’s age are busy being fathers to their children at home, the 40-year old NBA veteran is still lacing it up and playing world-class basketball against players young enough to be his sons. And for retired NBA swingman Antawn Jamison, that’s just another reason why Carter is half-man, half-amazing.

In a story by Rick Bonnell published Friday by the Charlotte Observer, Jamison, who scored over 20,000 points in a 16-year NBA career, tells Bonnell how he is awed by Carter’s staying power in the NBA.

“I don’t understand how he does it,” Jamison said of Carter, 40, who is preparing for his 20thNBA season.

“He can barely bend over to read his putts. To see him still be Vince Carter, and enjoying it. …He still brings something to the game.”

Jamison retired in 2014 so that he could focus more on what he considered to be a more important thing, which is being a hands-on and full-time dad.

“They sacrificed so much when I played. They need me to be home,” said Jamison, who nearly signed with the then-Bobcats in the summer of 2012 to be in Charlotte in the winter. He signed with the Lakers instead.

Carter is coming off a decent season playing for the Memphis Grizzlies, as he averaged 8.0 points with a 37.8 percent shooting from beyond the arc. He’ll enter the 20th season of his colorful NBA career this October donning Sacramento Kings threads after inking a one-year, $8-million deal this summer. Sacramento is the former slam dunk champion’s seventh NBA team.
