What? The Metrodome wasn't built to lure the Vikings or Twins from another city, and despite being a terrible stadium it lasted more than 30 years.So did we, it's called the Metrodome. The only difference I see is the clause to renovate.No. St. Louis built a really sterile, cheap stadium and convention center in the mid-1990s to help lure the team from Los Angeles, and then the team had a vague clause in the contract stipulating that the stadium be among the top-third in the NFL by 2014 (something like that), which is why they are talking about this now.
This isn't an indication at all that the Vikings stadium would be obsolete by 2030.
As Mullen noted, St. Louis is an example of a category of stadium that is built with the intention to lure a team to a city. Another prominent example is the terrible Tampa Bay baseball stadium. The problem with these is that soon after luring the teams, the stadiums are quickly found to be substandard.
That's obviously not the situation going on in Minneapolis right now.
