The NFL season hasn't started yet, but the Miami Dolphins already have suffered their first defeat. Florida lawmakers ended their 60-day legislative session on Friday without approving a deal that would have provided taxpayer support for a $350 million dollar upgrade to Sun Life Stadium, according to the Miami Herald. Had the legislature approved the deal, the people of Miami-Dade county would have voted on a referendum on May 14. The proposed deal would have raised up to $289 million for renovations by raising the Miami-Dade hotel tax from 6 to 7 percent. The Dolphins would have also had a shot at up to $90 million in state sales tax rebates. The rejected deal all but kills South Florida's hopes of hosting Super Bowl L or Super Bowl LI. The NFL had told the Dolphins that Miami would only be considered as a Super Bowl host if the team had a plan in place to renovate the 26-year-old stadium.
