Las Vegas Billionaire Sheldon Adelson is giving indications he could walk away from a deal to bring the Raiders to sin city. He suggested in an interview the Raiders want too much, and if they don’t want the deal he’s offered “Bye Bye.” He says he can live with or without the Raiders. Word in the sports community is Adelson wants part ownership of the team. The Raiders relocation is not certain even if Adelson and the team agree terms. Any move would require approval from three-quarters of NFL franchise owners.
