Yahoo Sports NFL reporter Charles Robinson gave a free-agency primer on Monday that included an almost-hard-to-believe nugget: Tampa Bay Buccaneers quarterback Mike Glennon, who has attempted just 11 passes over the last two seasons as he backed up Jameis Winston, may get a contract paying him $14M-15M per year.

Rick Stroud of the Tampa Bay Times reported last week that the Bucs offered Glennon a deal that would have made him the highest-paid backup in the league, exceeding the three-year, $21 million Chase Daniels received from the Eagles to backup last year’s first-round pick, Carson Wentz.

Glennon does have starting experience, though it’s been over two years since he last started a game.

But if Glennon does get the kind of deal that pays him $15 million a year, what sounds like a lot of money is really on the low end for starting-level quarterbacks now. Salaries at the position have skyrocketed; via OverTheCap.com, there are 13 quarterbacks who have contracts that average over $20 million a year, and 18 with an APY over $18 million per, led by Andrew Luck’s $24.6 million.

In a different way of looking at things, via Spotrac.com, 21 quarterbacks are currently set to count $15 million or more against the cap in 2017 – a number that does not include reigning Super Bowl MVP Tom Brady, who counts just $14 million against the cap this year ($1 million in base salary plus $13 million from his prorated guaranteed money) but does include Tony Romo, still on the Dallas Cowboys’ roster at a hit of $24.7 million, though Dallas and Romo will be parting ways, and if Romo is released he almost certainly won’t count as much against his next team’s cap.

Among those 21 quarterbacks are eight Super Bowl wins.

Here are the QBs in the $15 million cap club; you decide whether Glennon should be in their company:
