Less than a week after the Miami Dolphins were denied public funds for stadium upgrades, the prospects of South Florida hosting future Super Bowls — and possibly keeping the team — are cloudy, if not gloomy.When the Florida Legislature on Friday failed to even vote on taxpayer support for $350 million for improvements to Sun Life Stadium, it removed South Florida from serious contention to host the 50th Super Bowl. And on Sunday, Dolphins CEO Mike Dee told a Miami TV station that the future of the team staying in the area was “bleak.”Dee also said the team will not foot the bill for renovations without public money, and owner Stephen Ross ruled out a less-expensive, scaled-back upgrade.Ross, 72, has not threatened to move the Dolphins, but Dee said the situation would be challenging for any future owner.The Dolphins say they’re already heavily in debt and one of the NFL’s most leveraged teams, making upgrades impossible without taxpayer help.It’s always Tebow timeDespite his limited NFL success and coming off a season with the New York Jets in which he hardly played, Tim Tebow remains extremely popular among some fans.According to a survey released Monday by Forbes.com, the quarterback is America’s most influential athlete.Tebow had the most influence on fans, according to 29 percent of respondents, finishing ahead of Olympic swimmer Michael Phelps (25 percent), Jamaican track star Usain Bolt (23 percent) and Yankees shortstop Derek Jeter (22 percent).Forbes.com used surveys from Nielsen and E-Poll Market Research to determine the winner, and took into account Nielsen’s measurement for a player’s endorsement potential.The next-closest NFL player was Denver’s Peyton Manning, who replaced Tebow with the Broncos last off-season and finished fifth in the survey.The results of the poll might not have surprised the Jaguars, who on Monday created a petition asking President Obama to make Jacksonville sign Tebow as its starting quarterback. The petition received a few hundred signatures before being removed from the White House’s “We The People” website.New Jaguars general manager David Caldwell has said he isn’t interested in adding Tebow to his team.Briefly• Redskins: LB Brian Orakpo said Monday that his left pectoral muscle is healing well and he expects to be able to participate in organized team activities with the team later this month. He missed most of last season after suffering the injury in September.• Vikings: P Chris Kluwe, known for his outspoken stances against union leadership during the 2011 lockout and in support of gay marriage, was released. The move was expected because Minnesota drafted a punter, Jeff Locke, in the fifth round in April’s draft. Kluwe ranked 17th in punting last season and was due to make $1.45 million in 2013.• Browns: DE Armonty Bryant, drafted in the seventh round last month, was charged Monday with driving under the influence in Oklahoma. Bryant was arrested Friday near East Central University, where he played in college. Bryant pleaded no contest in October to a felony charge of marijuana distribution in a school zone, but coach Rob Chudzinski said the team drafted him believing he was “past his mistakes.”• Steelers: Hall of Famer Joe Greene is stepping down from his role in the team’s player personnel department to retire.
