Update: Duncan exercised his $5.6 player option for the 2016-17 season, but still remains uncertain whether he'll return to the Spurs for a 20th season, Adrian Wojnarowski of Yahoo! Sports reports.
Analysis: 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 averaged just 8.6 points and 7.3 rebounds per game, and it's likely his numbers and minutes would plunge even further during the coming season. However, when healthy, Duncan still shapes up as a great interior defender and a capable finisher around the rim.
