Free agency is in full swing. Over the past week, many top NFL free agentsĀ have re-upped with old teamsĀ or have signed with new teams that wanted their services.

As the weeks play out heading into the draft and offseason workouts, even more free agency signings will occur. But soon, lines will be drawn in the sand highlighting certain free agents who are not attracting one bit of interest.

In some cases, it is simply a matter of age creeping up, which makes older free agents less appealing. On a slightly sadder note, some younger veterans dealing with health issues or just too much negative baggage are getting ignored.

On that note, a couple of quarterbacks under the age of 30 headline this list of NFL free agents who should seriously consider retiring in 2017.
