3 of them are QB's - which I think is a different ballgame and maybe one of the few justified free agent splash plays. Except for Nick Foles who was signed as a backup and pulled a Jeff Hostetler.
Some were not big money / beginning of free agency guys but more reasonable short term deals - Chris Long, Blount. Torrey Smith? That's kind of a stretch.
Some of them played on squads that lost the Super Bowl (Owens)
Your list encompasses players from the last 20 years. 20 + years of free agent signings and a pretty small list. 5 of them from this year alone.
