Spurs' Tim Duncan: Exercises player option, unsure about returning

Duncan exercised his player option worth $5.6 million for next season Monday, but remains unsure whether he will return for 20th season, Adrian Wojnarowski of The Vertical reports.

According to Wojnarowski's report, Duncan is giving serious consideration to playing despite being 40 years old. Duncan's averages took a dip last season, as he posted just 8.6 points and 7.3 rebounds per game, and it's likely they'd dip even more next season along with his minutes. However, if healthy, Duncan still can serve as a great interior defender and capable offensive talent around the rim.
