Undrafted free agency is a madhouse for NFL teams after the draft ends, as everyone competes for the same players, and it becomes a bidding war like any other free agency. Despite these players going undrafted, in some instances, it is because teams will be drafting them because they know they may not be able to retain them in free agency.

The Los Angeles Chargers added a massive rookie class in Year 2 of the Jim Harbaugh overhaul via the NFL draft and a near-20-prospect undrafted free-agent class. Along the way, the Chargers reset various positions on the roster and sent some major messages to players already on the roster in the process.
