The city of Los Angeles has been without an NFL team for almost two decades, but Commissioner Roger Goodell believes the door remains open for pro football to return to a town that once housed both the Raiders and Rams.

"It still comes back to, 'Do we have the right solution in Los Angeles?' And that comes back to a stadium," Goodell said Thursday at The Beverly Hilton during a panel on Thursday Night Football. "Do we have a stadium that we feel can be competitive with the high-quality stadiums? I just came from San Francisco, from a ribbon-cutting for a new stadium (in Santa Clara) and we're excited about that and we're investing billions of dollars in creating those kinds of stadiums."

Said Goodell: "We would like to do that. We think there's a great opportunity to be successful (in Los Angeles). I think opportunity's starting to develop, maybe in part because we have that long-term planning in front of us."

Patriots owner Robert Kraft was on hand for the panel and told the room that league-wide "ownership is collectively very concerned that we don't have at least one team" in L.A.
