Hahn said that was the only way "to convince the public the second largest city in America needs a football team. I say, let's huddle."
"The naming rights are a big deal, a game-changer," Villaraigosa said. "It dispels the notion we're not going to build — or can't build — a new stadium."
At least one NFL team would have to agree to move to Los Angeles before the stadium is built. Of course, this being Super Bowl week, no NFL owners were at Tuesday's event.
However, influential Dallas Cowboys owner Jerry Jones took notice of it from Texas.
"To me, that is a major indication of the viability of a franchise in Los Angeles," Jones said. "They're a very credible group there that is attempting to build a stadium, and certainly the kinds of things they're doing, within the framework of the financial dollars that I'm seeing and hearing about, should work.… I'd say that's a very serious, positive thing that they have there."
Villaraigosa revealed he met secretly with NFL Commissioner Roger Goodell in December to discuss the NFL-to-L.A. situation, and added that he's met with at least one league ownership group interested in moving.
The mayor declined to name who but noted, "You saw the pictures," in reference to a Tuesday video montage that included scenes of Minnesota Vikings running back Adrian Peterson and roaring San Diego Chargers fans.
The Vikings, Chargers, Jacksonville, St. Louis, San Francisco, Buffalo and Oakland are the teams believed most likely to move based on current stadium leases or lagging attendance. Leiweke said he's been in talks with the Rose Bowl and Coliseum about serving as a temporary home to a team that would move.
"There's a little bit of putting the cart before the horse here without a team," stadium expert Ganis said. "The unquestioned key is getting a team. Is there a team that will move?"
Leiweke insisted Farmers' investment will help sway an NFL owner: "I talk to them every day. They're all aware they get a piece of this if they move here."
