SAN FRANCISCO – NFL commissioner Roger Goodell said stadium projects in Carson and Inglewood have made significant progress toward moving the league’s return to the Los Angeles-Orange County market but stopped short of saying that at least one team relocating is a done deal.

Goodell, speaking in a news conference at the conclusion of the league’s meetings Wednesday, also said Los Angeles could be considered as a candidate to host the Super Bowl in 2020 if there is a team in the market by the spring of 2016.

“I think there is significant progress but I don’t think it’s inevitable,” Goodell said of the NFL’s return to the nation’s second-largest market. “I think there is certainly momentum, there’s certainly opportunities.

“I can’t remember the last time we had two facilities that are actually entitled and are being being developed. That’s a very positive development. I think those are positive developments, but a lot more work has to be done.”

If a team or teams relocates to Los Angeles before next spring, they would be able to apply to host the 2020 Super Bowl. The NFL will select the 2019 and 2020 host cities at next March’s league meetings. Atlanta, New Orleans, Miami and Tampa Bay have already said they will apply to host one of those games.

“If there is a team that relocates to Los Angeles, at that point in time they could submit an application to be considered for Super Bowl LIV,” Goodell said. “And they would have to obviously qualify for that and then be included in the bid process.”

Goodell is considering moving up and condensing the window in which teams can apply for relocation. The current window for relocation applications is from Jan. 1 to Feb. 15.

“The window is something that is under my authority as commissioner, it’s something I can adapt,” Goodell said. “We’ve had a great deal of discussion already about the pluses and minuses of the L.A. alternatives and what’s going on in their local markets more importantly. So in some ways we’re significantly farther than we’ve been at any time for relocation in the past.

“So we have the ability to move that date up, I have the ability to change it and I’ve discussed it with the committee. We’ve discussed it with the membership. We also have the ability to shrink as far as the timeframe for when somebody applies and when the league can vote, make a decision. Those are both things I’m considering. I don’t expect that there will be any decision on that. One of the things we’ll want to balance is what’s happening in those local markets, making sure there’s sufficient time for them to at least to be able to make whatever proposals.”

Goodell said the league is still in the process of evaluating the financing plan for a proposed downtown St. Louis stadium recently presented by a stadium task force appointed by Missouri Gov. Jay Nixon.

“We heard directly from St. Louis a couple of weeks ago,” Goodell said. “It’s one of the things we’re evaluating. I don’t know if we’ve come to a conclusion on that to date. But there’s tremendous progress going on there. We’re going to make sure we give them the full evaluation, the full consideration and we’ll get back directly to them if we feel there’s any issues that need to be addressed.”

Goodell said he and other league officials have not had time to go over a plan for a Mission Valley stadium released by a San Diego task force Monday. The commissioner said the league has been provided no information from real estate consultant Floyd Kephart, who has an agreement with Oakland and Alameda County to come up with a plan for a development that would include a new stadium for the Raiders by a June 21 deadline.

Goodell was asked if the lack of information was frustrating.

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

Goodell said the league itself doesn’t have a deadline for when Kephart and local officials would have to present their plans to the NFL.

“We don’t have a deadline, but this is not a new issue that we’re all dealing with here,” Goodell said. “This is something the Raiders have been working on a stadium for years.

“This is something that’s been very publicly debated, so we do need to have a proposal from the people hear about how they’re going to be able to keep the Raiders here in Oakland and do it on a basis that is going to not only be good for the community but also good for the team long term. So that proposal is necessary. “
