There’s a strong chance several NFL teams won’t only be adding rookies this weekend.

There has been a flurry of trading in the league this offseason, and the draft will provide several franchises with the opportunity to deal a known quantity for future potential.

Here are a few players who could be on the move:

Philip Rivers

There was so much trade buzz surrounding Philip Rivers last week that it seemed all but certain he had suited up as a Charger for the final time. The team scheduled a private workout with Marcus Mariota in Oregon, and Rivers came out and publicly stated he has no interest in staying with the team if it moves to Los Angeles.

Now it’s being reported that the team is working to extend his contract past the 2015 season, when it will expire.

Should Charger fans read into those tea leaves as a positive sign that things are happening behind the scenes with the City and County of San Diego? That’s probably a stretch. But it looks like the Bolts aren’t willing to send Rivers AND their first round pick just to move up to No. 2. While he could be on the move, it seems it will only happen if Tennessee lowers its asking price.

Martellus Bennett

The Chicago Bears have made it clear they are interested in shopping their starting tight end.

Bennett, who skipped the team’s offseason workouts under new coach John Fox and offensive coordinator Adam Gase, has already drawn management’s ire. The team suspended him five days in August after starting a fight with rookie cornerback Kyle Fuller.

Bennett has caught 155 passes for 1,675 yards and 11 touchdowns in his two years in Chicago and has two years left on a four-year, $20.4 million contract.

Matt Forte

Bennett may not be the only one of Jay Cutler’s offensive weapons on the way out. it is possible that his three favorite targets — Forte, Bennett and the already departed Brandon Marshall — will all be in different uniforms next season.

Forte is heading into the final year of his contract and is sitting out the team’s voluntary minicamp as he seeks an extension. He also ruffled some feathers in the organization by skipping out on the presentation for the Brian Piccolo Award, which is one of the team’s highest honors.

The big question is how much the Bears could really get from another team for a running back about to hit 30.

Sam Bradford

For those convinced Chip Kelly is going to make some master chess move to pick up Marcus Mariota in the draft, it’s obvious that Bradford would be on his way out of Philadelphia before even playing a game as an Eagle.

It seems far-fetched that Philly will be able to pull off such a deal, but who ever saw Bradford being in this situation in the first place?

Adrian Peterson

There continue to be no easy answers for the Adrian Peterson situation. He wants out of Minnesota, but the Vikings are expressing no desire to grant him that wish.

General manager Rick Spielman has reiterated multiple times, including earlier this week, that they intend to keep him.

The Vikings would be foolish not to consider dealing the disgruntled back, but it’s likely no team is offering fair value for him in a unique situation.

Mike Glennon

Once Jameis Winston is officially named as Tampa’s first pick, Mike Glennon becomes irrelevant to the Buccaneers. But does he actually have any trade value?

It’s possible a team looking to find a backup quarterback who has experience but is still young enough to be polished into something more — say, Arizona — could be willing to part with a Day 3 pick for Glennon.
