One of the greatest, if not the best power forward to play the game is soon making his way out of the league. The San Antonio Spurs superstar Tim Duncan is inching closer to the twilight zone of his career but what can fans expect from "The Big Fundamental" in perhaps the last season of his career?

According to Bleacher Report, fans can simply expect the same old Tim Duncan from last season, who averaged 13.9 ppg, 9.1 rpg, and 3 apg. But, what more can fans see in the aging superstar?

According to his head coach Gregg Popovich, his defense will remain steady and he commended the forward's impeccable timing in altering or blocking shots. He believes that the forward's high basketball IQ is what keeps him right there with the elite.

"His timing is just impeccable," head coach Gregg Popovich told USA Today's Sam Amick. "He has a hard time jumping over the proverbial piece of paper, and he gets in position. He knows where to be. He's played long enough. He's got a great basketball IQ, and he has excellent timing, so he reads things well."

That is seconded by ESPN.com's Kevin Pelton as he also believes the defense of Tim Duncan will be one of the greatest in the history of basketball and when the time comes that he decides to call it quits, he will still be one of the best defensive retired player.

"It's unclear when the time might come that Duncan is no longer a good defender," Pelton wrote. "Perhaps age 50? While he's hardly mobile, Duncan can anticipate plays so well that he's almost always in place to offer help."

"His block rate has scarcely budged in his 30s, and Duncan remains a premier defensive rebounder because of his ability to secure missed shots in a crowd."
