NFL draft is in the books, but the front office for the Tennessee Titans are still busy lining up undrafted rookie free agents.

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 moment the Raiders made their final draft selection at 222 Saturday night, they began their work in luring in undrafted free agents. At the post draft press conference, John Spytek said the Raiders added 23 new prospects. With 11 of those coming via the draft, that means there are at least 12 others coming as undrafted free agents.
