With it seemingly clear that the Oakland Raiders are about to come the Las Vegas Raiders at about the same time the Golden State Warriors move across San Francisco Bay, it’s time for Oakland to concentrate its efforts into keeping the one remaining franchise — the Oakland A’s

The Raiders officially filed paperwork with the NFL last week to obtain permission to move the franchise from Oakland to Las Vegas.

It appears the Raiders have the cleared the most important hurdle — the money. With the NFL money is always the most important thing. Always.

The team says it has financial commitments to build a nearly $2 billion domed stadium in Las Vegas. Assuming those commitments are deemed solid, the proposed relocation plan will face its final major test when it goes before the NFL owners. The move must win the approval of 24 of the 32 owners. That vote could possibly come at the league’s meetings in Phoenix in late March.

The only real issue with the plan was that it involved $650 million from casino magnate Sheldon Adelson, but the NFL has rules against casino owners owning a stake in a team. Raiders owner Mark Davis told the NFL that he had secured a commitment from Goldman Sachs even if Adelson wasn’t able to participate.

The new plan commits $750 million in Clark County hotel room tax revenues, $650 from the Adelson family, and another $500 million from the Raiders and the NFL.

The Raiders showed little interest in a plan to redevelop is current Coliseum site that was hatched by former Raiders and 49ers great Ronnie Lott. Little wonder. When compared to the Las Vegas package it was a feeble effort.

While the City Council and county Board of Supervisors approved a framework to begin exclusive negotiations with Lott’s group, the framework had very little chance of success.

“There’s no way this would slow down a viable deal in Las Vegas,” Stanford sports economist Roger Noll told columnist Dan Borenstein in December. “Because it is non-binding and non-specific, it cannot be evaluated, and the NFL would not regard this as sufficiently complete to warrant consideration.”

If all goes according to plan, by the end of the decade Oakland, a city that once had three professional sports franchises, will be down to one — the Oakland A’s baseball team. The A’s haven’t exactly been the most willing tenants either. They spent years trying to move to San Jose, only to be blocked by the Giants’ market rights.

Rather than spending much more time chasing rainbows regarding the Raiders, the city of Oakland and the people of the East Bay should redouble efforts and figured out how to keep the A’s in the East Bay for the long term.
