The Brooklyn Nets have a 50/50 shot at keeping All-Star point guard Deron Williams according to a report on ESPN.com. Williams has allegedly narrowed his potential destination to two clubs, the Nets - whom he has been playing for since being traded there last season - and the Dallas Mavericks (Williams hometown team).

From the report :

Sources say Williams, in any case, already has instructed his representatives to advise any team that calls starting at 12:01 a.m. July 1 that he intends to either re-sign with the Nets or return to his hometown with the Mavericks after a glittering high school career in the Dallas area.

The Nets have expressed confidence all season in their ability to retain Williams, pointing to the team's forthcoming move to Brooklyn, increased off-court marketing opportunities for Williams with a team bound for New York and the fact that Russian billionaire owner Mikhail Prokhorov can offer a contract one-year longer than Dallas can worth nearly $100 million.

The maximum four-year offer the Mavericks can counter with approaches $75 million. But sources close to the process say Williams has ruled out every other suitor apart from the 2011 champions because of his respect for Mavs cornerstones Dirk Nowitzki and Jason Kidd and his belief that owner Mark Cuban would make the follow-up moves necessary to return Dallas to title contention after a first-round exit in the 2012 playoffs.
