The Miami Dolphins' Sun Life Stadium has played host to some huge games, including five Super Bowls, but changes are needed in an arena criticised for its atmosphere. And the Dolphins chiefs know that, as they've already started work on $350 million plans to transform the stadium. Every single seat has been ripped out, and huge corner chunks have been removed, ready for massive changes. After this season, a roof will be put in place, and the whole thing will be transformed into a European football-style area akin to the San Siro. Expect to see this stadium shoot up the list in 2016.
