At age 37, Tim Duncan is still amazing many people with his play with the San Antonio Spurs. As they continue to beat up on the Los Angeles Lakers and move forward in the playoffs, you can’t help but wonder how much longer Duncan will stay in the league.

With his “old man” style of game, it’s reasonable that he could probably play for a while. He doesn’t rely upon athleticism and speed the way many of today’s players do, which is part of the reason his game has stayed so steady over the years.

It looks as if Gregg Popovich will follow his superstar into retirement, whenever that is. Via My San Antonio:

“He’s a mentally unique individual in that he’s able to sustain the year-round workout regimen, both physically and (diet) wise,” Popovich said of Duncan’s resurgence. “He has an unbelievable feeling of responsibility for his place in the program and wants to sustain that performance that he brings night after night.”

“When he doesn’t think he can, he’ll stop. It might be in the middle of a game. I can see him walking off the court saying, ‘Nah, I’m not pulling my weight anymore. I’m gone.’ And he’ll walk. And I’ll be right behind him, like this. No pride, no nothing.”
