NFL commissioner Roger Goodell believes that the home of the Dolphins needs more upgrades if South Florida is going to be in the bidding for future Super Bowls. The 22-year-old stadium underwent $250 million in improvements in 2007 but is still falling behind the competition, Goodell said Monday. Miami will host the Super Bowl for a record 10th time on Feb. 7. "They've done a great job hosting Super Bowls here in the past," Goodell said. "The key thing is to make sure the stadium is state of the art and that it can compete with the stadiums in some of these other communities. They are moving to another level in some of these stadiums."
