By Ari Rabinovitch TEL AVIV (Reuters) - Casino mogul Sheldon Adelson said he is prepared to walk away from a deal to build a stadium that would help relocate the National Football League's Oakland Raiders to Las Vegas if terms offered by the team do not improve. "I negotiated to bring in the Oakland Raiders, an NFL football team from Oakland, because they don't have a stadium there, that I would build a stadium and rent it out to the Oakland Raiders," Adelson said on Wednesday during a travel technology conference in Tel Aviv. Adelson, who succeeded this month in getting legislation passed to enable the construction of the stadium, said his problems now involve negotiations with the Raiders.
