Goodell and several owners said in Houston that all things being equal, they would prefer that teams remain in their current markets. But the lack of a proposal for a new stadium in Oakland, and the commitment from lawmakers in Nevada to help pay for a stadium, have made Las Vegas an attractive alternative.

To keep all options open, the league continues to talk with the City of Oakland about how it might help the Raiders stay there.

Libby Schaaf, the mayor of Oakland, has said that the city is willing to provide the property for a new stadium and infrastructure improvements but will not help pay for a new stadium, which could cost more than $1 billion.

Davis said he was seeking to move to Las Vegas only because Oakland “came up with nothing, zero.” He insisted that his efforts to move to Las Vegas were not a way to gain leverage in negotiations with Oakland.

Regardless, Davis said the Raiders would remain in Oakland for at least two more years. The team, he said, has options to play in its current home, the Oakland-Alameda County Coliseum, in 2017 and 2018. He said getting a stadium built in Las Vegas in time for the 2019 season might be difficult.

He did say, though, that the Raiders were likely to play a preseason game in Las Vegas next year.

While the owners consider Las Vegas, they are also awaiting the results of a special ballot measure in San Diego in which residents will have a chance to approve tax increases to help pay for a stadium the Chargers want to build near downtown. Courts have yet to resolve whether the ballot measure can pass with a simple majority of votes, or if needs a two-third majority.

As part of the decision this year to let the Rams move to Los Angeles, the Chargers have until early January to exercise an option that would let them to move into a new stadium that the Rams are building in the Los Angeles suburb of Inglewood. If the Chargers forgo that option, the Raiders would then have the chance to move in with the Rams.
