NFL free agents who will get paid more than you think

There are still three Sundays left in the NFL regular season, but the shadow of the offseason is hovering for some teams and free agency is closer than it seems. That applies for players who are currently in the final year of their contracts, as the open market is within reach.

As we know, the open market can significantly impact a player's financial value. With multiple suitors comes the gift of leverage. Along those lines, let's take a look at the players who are soon to become free agents and might be worth more than you realize.

Mike Glennon, QB, Tampa Bay Buccaneers

The former second-round pick has 18 NFL starts to his name and should find himself in a comfortable situation this offseason. Tampa Bay has its franchise quarterback in Jameis Winston, so the price the Bucs are willing to pay Glennon likely has a ceiling. Meanwhile, the free-agent quarterback class looks weak (especially if, as expected, Kirk Cousins winds up back in Washington), and early evaluation of the 2017 draft class is that the QBs are just OK. Glennon has a 2:1 touchdown-to-interception ratio in his career and could be the most coveted open-market quarterback in a league where signal-callers are invaluable.
