The longer it takes the Sabres to make Daniel Briere an offer, the more tempting it is for the co-captain to become a free agent. Without ruling out the possibility of re-signing with Buffalo, Briere's agent, Pat Brisson, said Saturday the chances are increasing that his client will test the market once NHL free agency opens July 1. "It's different now," Brisson said, noting this is Briere's first opportunity to be an unrestricted free agent. "We'll see. It's getting closer and closer." Brisson, however, noted he's still open to getting a deal done with Buffalo. "We haven't ruled out anything," he said. "We're continuing to talk. We're very open-minded."
