Here are several speed bumps Seattle must clear to be considered:

*To host a Super Bowl, a stadium must have seating capacity for 70,000. CenturyLink Field is expandable to 72,000.

*A host city must have around 25,000 hotel rooms available within an hour of the stadium.

*The host city should have an average February temperature of 50 degrees, unless the stadium is covered. Seattle’s average is 44 degrees. However, the NFL waived that requirement for Super Bowl XLVIII, which will be held in 2014 at MetLife Stadium in East Rutherford, N.J., where the average is 30 degrees, according to the Super Bowl  website.

*The city must have an NFL team.

*Seattle’s stadium district likely couldn’t support a Super Bowl until after the completion of the viaduct-replacement tunnel project, which is slated for completion in 2016.

A Super Bowl is estimated to inject nearly $400 million into a host city’s economy.

• If cellphone strength at the team hotels isn't strong enough, the host committee “will be responsible [for erecting] a sufficient number of portable cellular towers.”

• The league has the option to install ATMs at the stadium that accept NFL preferred credit and debit cards, and the option to cover up ATMs that don't accept those preferred cards.

• The host city will pay all travel and expenses for a "familiarization trip" for the league  to inspect the region ahead of the Super Bowl.

• Local media is also asked to provide "significant advertising and promotional time" -- for free, of course -- in the weeks leading up to the Super Bowl.
