Since the NFL free agency period became official at 4 p.m. ET on Tuesday, rumors have been swirling about star players being traded or signing new contracts. As teams discuss possible deals and meet with free agents around the league, some of the top stars from the 2014 season could be wearing new uniforms in 2015.

Many of the league’s best free agents reportedly came to terms on contracts over the weekend, but deals could finally be made official on Tuesday afternoon.

Below is a look at the latest rumors surrounding the most active teams in free agency.

Philadelphia Eagles

No team has made more headlines than the Eagles this offseason. The team will look very different in 2015, especially on the offensive end. After trading LeSean McCoy to the Buffalo Bills and letting Jeremy Maclin sign with the Kansas City Chiefs, Philadelphia has reportedly traded their starting quarterback. According to ESPN, the Eagles and St. Louis Rams will swap quarterbacks Nick Foles and Sam Bradford.

The trade has only increased speculation that Philadelphia will draft Marcus Mariota. It’s been rumored that head coach Chip Kelly wants the Eagles to move up in the draft and select the Heisman Trophy winner, and Bradford could be the piece that helps them get a higher pick.

There had been reports that Frank Gore would sign with the Eagles, but the running back ultimately decided to play for the Indianapolis Colts. Still in need of a running back, ESPN’s Adam Caplan reports that there is mutual interest between DeMarco Murray and the Eagles.

New York Jets

Darrelle Revis might be the most highly coveted free agent that hasn’t reportedly signed a contract. After playing the majority of his career with the Jets and winning the 2015 Super Bowl with the New England Patriots, it appears the cornerback will sign with one of the two teams. ESPN’s Adam Schefter has reported that the Patriots sense Revis is headed back to New York, but New England is still pursuing the All-Pro.

Even if they don’t land Revis, the Jets have upgraded their secondary. New York will reportedly sign former Cleveland Browns defensive back Buster Skrine to a four-year, $25 million contract.

After trading for Brandon Marshall, Percy Harvin’s short-lived stint with the Jets appears to be finished. The Jets will reportedly cut the wide receiver, making him a free agent.

Baltimore Ravens

Minutes before the official start of free agency, the Baltimore Ravens traded defensive tackle Haloti Ngata. The team sent the veteran to the Detroit Lions for a fourth and fifth-round draft pick. Ngata was set to make $8.5 million in 2015, having been to five Pro Bowls as a member of the Ravens.

Wide receiver Torrey Smith announced on Monday that he wouldn’t re-sign with Baltimore, and it appears he’s found a new home with the San Francisco 49ers. He’ll reportedly sign a five-year, $40 million contract, joining former teammate Anquan Boldin as Colin Kaepernick’s top target. Kaepernick will likely return to San Francisco in 2015, despite rumors that he could be traded this offseason.

New Orleans Saints

The Saints made possibly the most shocking deal of the day, reportedly sending tight end Jimmy Graham to the Seattle Seahawks in exchange for center Max Unger and multiple draft picks. New Orleans will receive at least one first-round selection.

Since 2011, Graham has proven to be one of the best tight ends in the NFL, totaling 4,396 receiving yards, 366 catches and 46 touchdowns in the last four years. He battled injuries in 2014, catching 85 passes for 889 yards, though he didn’t miss a game.

Having been to the Pro Bowl in three of the last four seasons, Graham immediately becomes the best receiving option on the Seahawks. Seattle hasn’t had a 1,000-yard receiver since 2007, and starting tight end Luke Wilson caught just 22 passes for 362 yards in 2014.

New York Giants

The Giants have already placed the franchise tag on Jason Pierre-Paul, and they’ve spent the first day of free agency making smaller signings. New York is reportedly set to sign wide receiver Dwayne Harris, running back Shane Vereen and right tackle Marshall Newhouse.

Antrel Rolle could be headed elsewhere after five seasons with the Giants. The safety is visiting with the Chicago Bears, and even if the two sides don’t come to terms on a deal, he could be playing for a different team next season.
