Mark Davis and the Raiders received official NFL approval on Monday to relocate to Las Vegas, and naturally, the city of Oakland is not pleased. They could not come up with the kind of public funding Las Vegas offered ($750 million direct, $200 million in infrastructure), and the NFL has made it clear money comes first for its franchises.
The Raiders have said they will remain in Oakland for the 2017 and 2018 seasons, but are unsure about 2019. It will likely take three years to build their new stadium, which means they need a home for 2019.
