No retirement plans for Tim Duncan yet

At 38, Spurs legend Tim Duncan knows the end of his NBA career is near. But with his fifth championship in his sights, Duncan said at Wednesday’s media availability that he has yet to seriously contemplate retirement.

“I’ve not come to that point yet,” Duncan said. “I don’t know when I’m going to retire. I don’t know what the factors are going to be. I don’t know any of that and I don’t care about any of that stuff right now. I’m not thinking about that. It will happen when it happens. I’ll feel it and I’ll now it and I’ll call it a day.”

Duncan has a player option to return for what would be his 18th NBA season. Former NBA coach George Karl had speculated earlier this year, basing his information on unnamed sources, that Duncan will retire. But Duncan and Spurs coach Gregg Popovich roundly dismissed that notion as the future Hall of Famer continued to put up quality numbers, averaging 15.1 points, 9.7 rebounds and 1.9 blocks.
