If the offers for Antoine Walker remain sub-par, the Mavericks won't pull the trigger on a deal.

Mavs' president of basketball operations Donnie Nelson said the club is not opposed to starting training camp with the 6-9 forward still with the team.

"We're getting a lot of calls," Nelson said. "I think people realize that Walk has value, not only because of his ability but because he's going into the last year of his contract. Wherever he plays, he's going to have a big season. But there's nothing close right now."

The Mavericks are believed to have interest in Philadelphia's Samuel Dalembert and/or Willie Green (though more players would have to be included to make the deal work).  Glenn Robinson is on the block in Philadelphia, but the Mavericks are not too high on acquiring Big Dog.

The Knicks and Isiah Thomas also covet Walker and may have some pieces to make a deal work, especially through a multi-team deal.
