NFL Commissioner Roger Goodell on Wednesday echoed what Raiders owner Mark Davis said a day earlier: He’s waiting to hear from Oakland.

At the NFL Spring Meetings at the Ritz-Carlton in San Francisco, Goodell said the city of Oakland hadn’t submitted a proposal for a new stadium that would keep the Raiders in the Bay Area. On Tuesday, Davis said he had received “nothing in response” from Oakland and Alameda County about a financing plan that would provide $400 million for a proposed $900 million stadium.

The silence contrasts with San Diego and St. Louis, other cities pushing to keep their teams. On Wednesday, for example, Goodell said, St. Louis had made “tremendous progress” in its effort to keep the Rams. Civic leaders unveiled plans in January to build a stadium along the Mississippi River that could cost $1 billion.

Goodell was asked if he was frustrated by Oakland’s inaction.

“I don’t know if it’s a point of frustration,” he said. “But it’s certainly a point of information.”

Before Goodell spoke, NFL Executive Vice President Eric Grubman sounded similarly miffed. Grubman, who is overseeing the league’s Los Angeles initiative, said his visits to Oakland in recent years had produced a series of unrealized promises and no progress.

“No results have been produced,” Grubman said. “That, to me, is going backward. Because the time has shrunk, but the probability hasn’t gone up.”

Schaaf awaits proposal, too

Meanwhile, Oakland Mayor Libby Schaaf said the city wasn’t ambivalent about keeping the Raiders. Schaaf is waiting for a finance proposal from the city’s private development partner, Floyd Kephard, but it’s not due until June 21. Schaaf said she spoke with Grubman on Tuesday morning and is tentatively scheduled to meet with Goodell when she is in New York early next month.

“We share the NFL and Raiders’ frustration,” said Schaaf, who took office in January. “The last (city) administration produced a string of unsuccessful development partners and, frankly, some false promises … (Grubman) acknowledged frustration with the past team, but he also seemed very committed to working with us in coming up with a solution here.”

Schaaf said the solution in Oakland is more complex than in San Diego and St. Louis because the Raiders share a stadium with the A’s and the land is owned jointly by the city and Alameda County. She noted that the city has completed zoning and environmental clearance to create a Coliseum development area that could support the project.

“While I’ve been clear that I can’t support putting more city money into stadium construction, I am committed to providing the Raiders with more clarity about other ways the city can contribute,” Schaaf said. “I recognize that also has been a frustration to them. And that’s something I’m committed to correct.”

The Raiders, of course, are moving forward with Plan B: a proposed $1.7 billion stadium they would share with the Chargers in Carson (Los Angeles County). On Monday, the teams hired former 49ers executive Carmen Policy to spearhead the campaign for the team to relocate to Los Angeles. On the same day, they finalized a deal to purchase 168 acres on the proposed site.

Rams buy land in L.A.

The Rams are also exploring a move to Los Angeles. Owner Stan Kroenke has purchased land for a proposed $1.86 billion stadium in Inglewood.

Goodell said Wednesday that if a team is playing in Los Angeles by 2018, it will be eligible to bid on Super Bowl LV, which will be played after the 2020 season. Atlanta, Tampa Bay, New Orleans and Miami are the four teams bidding to host Super Bowls after the 2019 and 2020 seasons.

On Wednesday, Colts owner Jim Irsay said there would be at least one NFL team in Los Angeles in the “coming years.” Goodell wasn’t quite as certain.

“I think there is significant progress, but I don’t think it’s inevitable,” Goodell said. “There is certainly momentum. There are certainly opportunities. I can’t remember the last time we had two facilities that were actually entitled and being developed. That’s a positive development, but a lot more work has to be done.”
