NEW YORK — The NFL is moving slowly toward Los Angeles, and rapidly around the rest of the globe.

On the same Wednesday that the owners approved an extension and expansion of the international series of regular-season games, they discussed at length the desire of three teams to relocate to LA. The Rams want to leave St. Louis, the Chargers want to vacate San Diego, and the Raiders seek to move from Oakland.

Commissioner Roger Goodell expects owners will vote on franchise relocation, but when is another matter.

Goodell said the owners expressed interest “in wanting to be there, but also recognize we need to find solutions. Our relocation policy is very important.”

So the league is being cautious and thorough.

“When you start out with nothing and you are trying to find a solution, you try to find all the pathways that can lead to success,” said Eric Grubman, the NFL’s point man for relocation to LA. “If you find one, people aren’t necessarily optimistic it’s going to be successful because there’s a failure rate. If you find 100, then people are very optimistic. When we attacked it, we had to find more than one thing that can work.

“So what happens when you find more than one thing that can work and it’s in the NFL and it involves multiple owners and multiple cities? Then suddenly the picture becomes very murky because not everyone can get exactly what they want. And that’s the scenario that’s most likely to play out.”

Los Angeles has not had an NFL franchise since 1995, when the Rams and Raiders left. The current timetable calls for submission of applications to relocate in January, when the owners could vote.
