The South Florida Super Bowl Host Committee met with NFL executives Tuesday to present the Miami Dolphins' bid to host Super Bowl L.
Dolphins chief executive officer Mike Dee tweeted a picture showing committee chairman Rodney Barreto making the presentation.
"I think a lot of our efforts and energy are going to be hinging on the fact that we get these improvements at the stadium," Barreto told reporters during a conference call.
The Dolphins say Sun Life Stadium needs at least $350 million in improvements to remain competitive with newer stadiums around the NFL. Miami-Dade County voters will decide whether to contribute to the modernization plan in a referendum in May.
"Chances for us are appreciably less if we don't have a facility that's different from the one we have today," said Dee.
The 30-year economic development grant struck between Miami-Dade Mayor Carlos Gimenez and the Dolphins includes a non-relocation agreement. The Dolphins have offered to pay the county and the state back the money it receives from a sales tax rebate of $3 million a year for 30 years.
The state legislature is considering a bill that would authorize the rebate and also raise the hotel bed tax. Under the Senate version of the bill, the Dolphins would have to compete for that money with other professional sports franchises in the state.
Dee added owner Stephen Ross wouldn't pay for the stadium improvements if the legislature or voters denied him.
The Dolphins and San Francisco 49ers, who will move into a new stadium next year, are vying for Super Bowl L in 2016. The loser will compete against the Houston Texans to host Super Bowl LI in 2017.
NFL team owners will announce the locations of Super Bowls L and LI on May 22 in Boston.
