With a heartbreaking loss to the Oklahoma City Thunder, the San Antonio Spurs' fantastic season came to a disappointing close.

Just over a week ago, they held a 2-0 advantage of the Thunder. They looked like they were headed back to a championship after a four year drought. Last time the Spurs went to the Finals it was in 2007.

Year by year, their chances of winning become slimmer. 

Their superstars are aging. That point was made clear by analysts in every series the Spurs played in during the postseason. Could they keep up with the Lob City Clippers? Would they lose the foot race against the Thunder?

Tim Duncan is the longest tenured Spur. He has enjoyed watching the team succeed as his career progressed. He has been in the playoffs every season of his 15-year career.

Duncan has also been a big reason why the Spurs have won four championships since 1999.

Tony Parker is no longer in his 20's and because of players like Duncan, he has also enjoyed playoff trips every year of his career.

Parker looks like he can still compete as he helped guide the Spurs to the best record in the NBA, only the Chicago Bulls were able to match the Spurs record.

Duncan and Parker teamed up and helped the team win 20 consecutive games, placing them in the same talks with championship teams like the 1972 and 2000 Los Angeles Lakers and 1971 Milwaukee Bucks.

The good news for the Spurs is that they get the same core of players back next season. DeJuan Blair is balancing on a team option. Boris Diaw replaced Blair in the lineup half way through the season.

Duncan is an unrestricted free agent but he has expressed that he does not want to leave San Antonio.

The Spurs should begin establishing who they want to be the future of the franchise. Parker is already 30 and Manu Ginobili's reckless style of play have not allowed him stay healthy.

The Spurs have 15 straight years in the playoffs. Look for their front office to make the appropriate moves, keeping the San Antonio Spurs in contention for years to come.
