Sources: Mavs Fear Nets Keep Williams

As executives make their final preparations for the draft and engage in serious trade talk over the next 48 hours, Deron Williams’ impending free agency looms large. Four rival executives and a fifth person familiar with Williams’ thinking told CBSSports.com Tuesday that the Mavericks are becoming increasingly worried that the All-Star point guard will stay with the Nets when the free-agent floodgates open Sunday.

While optimists in the Mavs’ camp are holding out hope that they still have a “50-50″ chance of landing Williams, who grew up in Dallas, executives working the phones Tuesday have detected a real concern from the Mavs that Williams will opt to join the Nets in Brooklyn next season. Free agency opens at 12:01 a.m. ET Sunday, and Williams will have a very clear financial decision in front of him.

Under new CBA rules, the Nets can offer Williams a five-year deal worth approximately $100 million — one year and about $26 million more than the Mavs, the only other team the All-Star is believed to be considering.
