The 2015 NFL draft may be a thing of the past, but the fun is just getting started for NFL teams still on the hunt for potential roster upgrades and sleepers.
Undrafted free agency is a chaos-riddled time of year when every player not selected in the draft is free to sign with a team of their choosing.
Teams use this period to round out summer and preseason rosters, provide competition and perhaps even find players who can make final rosters. Look at what the Cincinnati Bengals got out of a player like Vontaze Burfict a few years ago.
