Bill Duffy, the agent for center Andris Biedrins, said Sunday there will be no contract extension for his client after negotiations with the Warriors on a long-term deal ended with "significant" differences on Biedrins' current value.

Duffy was seeking a five-year deal worth substantially more than $50 million. The Warriors' offer was substantially less than $50 million. The gap was large enough that talks did not progress to a serious degree.

"Their opinion is that they can pay him that next summer," Duffy said. "That's true, but we think his value will increase.

"The way this game is evolving, he's one of the top five young interior players in the NBA, in my opinion. He's 21 years old, he has the experience, he's confident and everyone knows his character and work ethic."
