Mark Davis and Sheldon Adelson continue to negotiate a deal for a stadium in Las Vegas for the Raiders that would include $750 million in taxpayer money.

The past two weeks have been particularly difficult for Davis and Adelson.

Adelson has a reputation for driving hard bargains and he is expected to push for partial ownership of the Raiders and a path to control the franchise.

Davis still hasn't dismissed a proposal that could keep the Raiders in Oakland, perhaps as leverage against Adelson in their negotiations.
