The best players on the free-agent market have all been signed by this point in the offseason, and teams have turned their attention to the NFL draft, less than a month away.
Perhaps the biggest reason a lot of players are still on the market is that they aren’t impressive on the field anymore. If teams believe they can get an equal player in the draft, it would benefit them to wait until after the draft before considering a pricier veteran.
Some of the most common flaws are age and health, but there are plenty of other reasons teams aren’t going crazy signing the remaining free agents. A player might not be a scheme fit for teams that have a need at certain position, plus free agents almost always cost significantly more than draft picks. There are also off-field concerns that could be preventing a team from expressing interest in a certain player.
Every player who remains unsigned has some type of flaw or weakness that is keeping them on the market, even if they have a lot of traits that could be useful to NFL teams.
