Tim Duncan turned 39 just a few days ago and he seems to be enjoying this playoff run more than he has in the past.

Duncan has now played in 239 career playoff games.

"It's just a realization of mortality, I guess," Duncan told Yahoo Sports late Tuesday. "I know my time is winding down so I'm enjoying it more."

Duncan is making $10.3 million in the final year of his contract and his future remains uncertain.

"The reason their franchise has been great is Pop and [Duncan]," Doc Rivers told Yahoo Sports. "The reason is [Duncan is] a superstar and he cooperates with his coach. He allows him to be the leader and the coach of the team. And he's the second leader. And I think that is so important.

"That should be [Duncan's] legacy. Forget the basketball part. He's allowed that franchise to be great because it's never been about him."
