Local officials made no offer to restrict betting on NBA teams in a pitch for a franchise sent to commissioner David Stern on Thursday.

The proposal, requested by Stern in February, emphasizes Nevada's gambling regulatory record and argues the system "should provide sufficient cause for the association to permit a franchise to exist comfortably in Las Vegas without concern of corruption or interference by unsavory individuals."
 
Stern has said he was opposed to expansion into Las Vegas as long as gambling on teams was allowed. But during NBA All-Star week in Las Vegas, the commissioner invited a proposal from local officials that would address his concerns, a move many took as a sign that his opposition was softening.
