Bradentonian, what high impact free agent players are you referring to?
I am not so sure but here is a start (Note that some of these players were re-signed before hitting free agency).
2004 NFL Free Agent Listing
Below is a list of Free Agents entering the offseason for 2004. Results are listed by team.
UFA = Unrestricted Free Agents - free to negotiate with any team though the team has the right to franchise or transition them.
RFA= Restricted Free Agents - team will have opportunity to tender an offer to players and may receive compensation from a team that signs a player.
EFA= only team with the players' rights can negotiate with that player.
***= Franchised; ^^^ = Transitioned
