The NFL Draft is now in the rear-view mirror and teams have a better outlook on what they need going into training camp. Also, a few teams cut some veterans after recently drafting their replacements.
There are some former Pro Bowlers still unemployed. Some of them are due to salary cap issues and some are more for off-the-field stuff.
Some of these free agents will probably go unsigned until preseason games begin as teams will suffer injuries. A few may even go into the regular season without a job.
