Tim Duncan could have easily gone out on top, with his fifth NBA championship trophy under his arm and his health intact just a few months after his 38th birthday.

There's just no way. Duncan is having too much fun with his San Antonio Spurs coaches and teammates, and he's playing too well to call it quits now.

Duncan has decided to exercise the option on his contract for 2014-15 and will return next season, the team announced Monday. Since he was drafted No. 1 overall in 1997, Duncan leads all NBA players in wins and has won two MVP awards and three NBA Finals MVPs.
