NFL free agency grades are worth a little more than NFL Draft grades because at least these players have played in the NFL, but it’s hard to say how a signing will work out before you see that player on the field with his new team.

With that being said, Seth Walder of ESPN gave the Titans an A- for the Arden Key signing.
