Pistons guard Richard Hamilton isn't sure if he'll sign another contract in the NBA.

His current deal runs through the 2012-13 season.

"I don't know," Hamilton said in an interview with the Detroit Free-Press.

"When you hit 35, you take it one year at a time. I know that at a certain time being around my family (will take precedence). I'm going to walk away. I'm not going to be one of them guys that just sits around and holds on. When I feel as I'm not going out there and playing as hard and the game is not that important to me no more, I'll stop playing."
