With most of the big names already finding their new homes for 2018, we now head into what we call the "second wave" of free agency.
At this point, there are still players that can contribute to an NFL roster, but at varying levels.
Some might be veteran mentorship, depth, or a low-end starter for a team in need of the position.
For example, the Kansas City Chiefs locked down quarterback Chad Henne, according to Mike Garafolo of NFL Network.
Henne won't actually play for the team, but instead, he'll mentor second-year and the Chiefs news starting quarterback Patrick Mahomes—a very valuable asset to have.
