A failed attempt to upgrade Sun Life Stadium appears to have hurt Miami as NFL owners awarded Super Bowl 50 to San Francisco and Super Bowl 51 to Houston.

In the Dolphins’ first organized team activities of the year open to the media, new cornerback Brent Grimes showed his impressive athleticism.

Reshad Jones was back at work Tuesday. Randy Starks was still nowhere to be seen.

One of two things is going to happen Tuesday when the NFL awards Super Bowls 50 and 51:

Safety Reshad Jones, unhappy with his rookie contract, missed Monday’s conditioning session and may miss OTAs.

With a tax-subsidized renovation of the Dolphins’ stadium ruled out, South Florida pins its hopes for landing Super Bowl 50 on promising the biggest party the region has ever seen.

The University of Florida’s Mike Gillislee became the latest Miami Dolphins draft pick to sign with the team, agreeing to a four-year rookie deal expected to pay an estimated $2.3 million.

Chad Johnson, the former Miami Dolphins wide receiver who went on the lam after failing to check in with his probation officer, spent Monday in the Broward County jail before posting bail and being released.

Dolphins players floated out from Miami Beach to try and land the biggest catch – and a nice jackpot for the local community.

Despite a flurry of offseason moves, the Dolphins still have ample cap space and will continue tweaking the roster.

Miami general manager Jeff Ireland and six other Dolphins scouts attended FIU’s Pro Day in March.

Dan Carpenter, Miami’s kicker for the past five years, will have to outperform rookie University of Florida product Caleb Sturgis in training camp if he intends to make it six years.

The Dolphins are totally new. They have new uniforms. They have a new logo. They’ve committed a whopping $204 million in new contracts this offseason with $91 million of that hefty sum guaranteed to 14 players.

Chad Johnson, the former football player and ‘Dancing with the Stars’ contestant, has been ordered to jail for violating his probation.

It’s only May, but some of the Dolphins’ leaders have been stating publicly that a certain level of success is expected this season.

The Dolphins spent Tuesday with a group of local school kids at a Dave & Buster’s, teaching them about living a healthy, fit life.

Dolphins quarterback Ryan Tannehill will look you in the eye and tell you that “last year wasn’t good enough,” that he simply must improve his completion percentage (23rd in the league) and third-down performance (30th).

The Dolphins, still smarting from a legislative defeat in an effort to upgrade Sun Life Stadium, are considering all their options in order to find a long-term solution.

The San Francisco Bay area is clearly the favorite to land the most significant of the NFL’s signature games in a couple of weeks. Super Bowl 50, a game that will not only celebrate the two finest teams of the NFL’s 2015 season, but also recall half a century in which professional football became the national game, is going to be hard to wrest from the folks out west.

History reminds that people in Baltimore, Cleveland, Houston, St. Louis and Los Angeles ignored the early signs of an NFL franchise getting ready to uproot long before their teams left town.

Ross joins his fellow billionares in pledging to give away his money to charitable causes. But he will continue exploring tax-funded help to upgrade Sun Life Stadium, a top aide says.

With Jonathan Martin shifting to left tackle to replace Jake Long, the Dolphins signed 329-pound Tyson Clabo to play right tackle.

The Dolphins sounded more like losers on this spring Sunday than they usually do on fall Sundays.

Dion Jordan, drafted third overall by the Dolphins in April when they traded up to get him, is poised to be the franchise’s next great pass-rusher after being molded in life through adversity.

Mike Gillislee, Jelani Jenkins and Caleb Sturgis grabbed the attention during the first day of the three-day Dolphins camp.

Dion Jordan didn’t exactly jump out of the blocks to start his NFL career, and that’s not an aspersion but simply the truth. The Dolphins first-round pick is still recovering from shoulder surgery, which everyone knew about, so when most of the other rookies got busy trying to impress coaches during Friday’s rookie camp practice, Jordan simply watched.

After each draft, general manager Jeff Ireland runs through his team in his mind to see if he can project something close to a final 53-man roster.

The Dolphins are hoping their upcoming rookie camp will address concerns heading into the 2013 season.

After registering to work in a $350 million renovation of Sun Life Stadium, applicants were handed pledge cards where they could sign their names to supporting using hotel taxes to help pay for it.

The Dolphins hope to strike a deal with an offensive tackle very soon after working out right tackles Eric Winston, Tyson Clabo and Winston Justice on Wednesday and left tackle Bryant McKinnie earlier in the week.

The Miami Dolphins addressed a number of needs during the NFL Draft, but general manager Jeff Ireland might have to go through free agency to find an upgrade at left tackle.

Dion Jordan says he’s ready form a fearsome pass-rushing tandem with Cameron Wake. First, he must get his shoulder healthy.

A daylong, often tedious endeavor, the final day of the NFL Draft got awfully interesting, awfully fast.

The names the Miami Dolphins added in the draft this weekend start to blur after a while because general manager Jeff Ireland did a fine job of gathering a lot of picks for this draft and then filled his needs as well as desires over three exhilarating days.

LeBron James and the champion Heat are rolling impressively through the NBA playoffs, but it was the Dolphins dominating local conversation this week — the Dolphins, who once owned the Miami sports market and are acting like they mean to win it back.

Let us marvel in open-mouthed awe at this magic trick the NFL unveils annually, waving a wand over a hypnotized audience to much applause when all this league is really doing is just selling your hope right back to you. Well, that’s not fair, actually. That’s not all the NFL is doing. It is also conspiring as a monopoly with a corrupt NCAA cartel to create a free-labor minor league for its multibillion-dollar industry, plus signing up gladiators who are dying earlier and in more pain than the rest of us. But we lap this NFL Draft up every year like thirsty hounds at a bowl because you won’t find a lot of introspection at the biggest and best parties.

The Dolphins drafted two cornerbacks and an offensive tackle and traded receiver Davone Bess for more picks.

The grudge Tony Sparano held after the Dolphins’ surreptitious courting of Jim Harbaugh in early 2011 “damaged the whole organization,” owner Stephen Ross said on Dan Le Batard’s show on 790 The Ticket on Friday afternoon.

Years from now when hindsight puts this NFL draft into focus, we’ll know if the Dolphins decision to improve on defense instead of turning the offense into a loaded point-manufacturing machine was the right way to go.

The Senate again delayed voting on a bill allowing the Miami Dolphins to use taxpayer money to renovate the stadium. The House is waiting for the Senate to act.

The days of being safe, boring and mediocre passed into history Thursday.

Do we trust the Dolphins yet? More to the point, do we trust general manager Jeff Ireland?

Picture this: Biscayne Boulevard transformed into a mile-long street party, featuring live concerts, a Ferris wheel and more.

New year, new team and new look — in most every way.
