Even though the Vikings have never actually threatened to leave the Twin Cities, the chilling possibility of relocation has long shadowed their campaign for a new stadium.
Owner Zygi Wilf has pledged, practically from the day his family took over the team in 2005, that he wouldn't move the Vikings. That doesn't mean the Wilfs couldn't sell the team to someone who might want to leave for more lucrative stadium digs -- say, in Los Angeles, where two stadium plans are forging ahead.
But moving the Vikings wouldn't be an easy sell, sports business experts say.
The NFL's elaborate relocation process -- splashed over six pages on its media website -- and the league's avowed interest in maintaining geographically diverse teams with proven fan bases weigh against the Vikings moving anywhere in the near future.
NFL officials declined to comment for this story. But in the end, the team's portability rests with the NFL's 32 clubs -- three-fourths of which would have to approve the Vikings' exit from the Twin Cities. Much will depend on what the NFL decides about Los Angeles: whether to put one or two teams there, and how.
"The brand name of a league depends on its longstanding franchises, and certainly the Los Angeles Vikings won't be as attractive in branding as the Minnesota Vikings," said Rod Fort, a sports management professor at the University of Michigan. "There should be Vikings playing in a frosty land. That's the whole idea of it."
The NFL considers local corporate support critical to a team's success, and Minnesota ranks high on that score. Only five of the NFL's 32 markets have more Fortune 500 companies than the Twin Cities.
Minnesota even enjoys a measure of protection in the halls of Congress. With the NFL's lucrative antitrust exemption for broadcasting under constant scrutiny, it's noteworthy that both the state's U.S. senators, Amy Klobuchar and Al Franken, sit on the Senate's Antitrust Subcommittee.
