IRVING, Texas — NFL Commissioner Roger Goodell isn’t saying whether he’s optimistic that San Diego and Oakland can keep their teams, while Indianapolis owner Jim Irsay considers both franchises all but gone.

Dean Spanos of the Chargers and the Raiders’ Mark Davis weren’t talking at the NFL owners meeting Wednesday. And no new specifics were revealed by Goodell a day after city and county officials in Oakland agreed to open negotiations with an investment group on a $1.3 billion plan for a new stadium.

“As you know, these issues have been going on for an awful long time,” Goodell said. “The challenges of getting stadiums built is something that we’ve worked very hard on. We have not made great progress in Oakland and San Diego. There is not a stadium proposal on the table that we think addresses the long-term issues of the clubs.”

The Chargers face a Jan. 15 deadline to decide whether to join the Rams in Los Angeles, part of a deal struck almost a year ago when owners agreed to let the Rams leave St. Louis. A Chargers-written ballot measure asking for $1.15 billion in increased hotel taxes to help fund a new downtown stadium was soundly defeated last month.

Earlier this year, Davis said he was committed to moving the Raiders to Las Vegas, where a $1.9 billion stadium project has been approved.
