If the Nets win the lottery to select Anthony Davis, it will not be enough to sign Deron Williams as a free agent, according to sources.

"It's Dwight Howard or bust," said a league source who has spoken to Williams.

Williams doesn't want to wait for Davis to develop and won't re-sign with the team unless they become an instant contender.

The Nets believe they will be able to retain Brook Lopez in a potential trade with the Magic if they win the lottery.

Sources say Howard regrets opting into his contract and seeks a trade before the 12-13 season. But the Nets become a far less appealing destination if Williams leaves and that is why Howard's camp is putting pressure on the Magic to do a deal once a general manager is in place.
