The NFL is all about quarterbacks, and free agency is no different. Here is the latest that is happening with the top quarterbacks on the market:

Colin Kaepernick

Contenders: Broncos, Jets and Browns

While the Broncos’ interest in trading for Colin Kaepernick is legit, John Elway is in “no rush to do anything,” a person informed of the team’s plans told USA TODAY Sports' Lindsay H. Jones.

The person spoke on condition of anonymity because Elway has not commented on the team’s plans beyond a statement he issued Wednesday night in which he said the team was looking at available quarterbacks.

And Kaepernick in Denver would make sense for plenty of reasons. The Broncos evaluated him in 2011 when he was coming out of the University of Nevada, even bringing him to Englewood, Colo. for a visit. The Broncos ended up sending the No. 36 pick in that draft to San Francisco, and the Niners used that pick to select Kaepernick.

He fits the physical profile that Elway likes in his quarterbacks – big, strong-armed and mobile. Kaepernick could function well in a Gary Kubiak offense that is built around the running game and also requires a mobile enough quarterback to move the pocket for bootleg plays.

One remaining question though about Kaepernick is his health after he underwent a series of surgical procedures on his shoulder, knee and right thumb since he was placed on injured reserve by the Niners last fall. None are believed to be long-term injuries, but his recovery is something that will have to be considered by both the Niners and any team looking to acquire him.

The Browns are also in the mix, according to several reports, as are the Jets to a lesser extent.

But the Broncos remain the favorite to land Kaepernick should the 49ers decide to trade him.

Ryan Fitzpatrick

Contenders: Jets and Broncos

Now that Osweiler’s deal is reportedly done, Fitzpatrick could be the next piece to fall into place. He threw for career highs in passing yards (3,905) and touchdowns (31) in his one season with the Jets. Because of his familiarity with offensive coordinator Chan Gailey, Fitzpatrick’s best fit is clearly with the Jets, but Fitzpatrick has decided to test the market.

Reports say the Jets and Fitzpatrick, 33, remain far apart on a deal, but it doesn't seem any suitors have stepped up yet -- partly out of fear the QB's agent would use any offer as leverage with the Jets.

The Jets had Robert Griffin III in for a visit on Friday. Smokescreen? We will see.

Six telling trends before NFL free agency begins

Robert Griffin III

Contenders: 49ers, Jets and Rams

Had a visit with the Jets on Friday. The start of the process for him.

He will be another QB who has to wait for the trickle-down effect. When teams find themselves with an opening, he might be on the their speed-dial.

Case Keenum and Nick Foles

According to USA TODAY Sports’ Tom Pelissero, the Rams placed a first-round restricted free agent tender, which means that if another team goes after him, they will need to forfeit a first-round draft pick to Los Angeles. With the Broncos having a clear need at quarterback, this protects that player that coach Jeff Fisher has said will enter the offseason as the starter. Keenum previously played for Kubiak with the Texans.

Zach Mettenberger and Mike Glennon

Contenders: Undetermined

They looked like potential NFL starters until Mettenberger's Titans drafted Marcus Mariota last year while Glennon's Buccaneers took Jameis Winston. Now Tennessee has even added Matt Cassel to the mix. Mettenberger and Glennon are both big-bodied, strong-armed — though fairly immobile — players who their current clubs could be better off dealing now rather than let them escape for nothing later.

Johnny Manziel

Contenders: Undetermined

He was waived by the Browns on Friday. Teams expected to keep their distance. .
