Yep! It worked for me. I unretired Brady, Palmer, Romo, Brees and Gates for my franchise and retired Megatron, Beast Mode, Raji, and Jerrod Mayo using that table. I also set the players to team 109 or 114? in the PLAY database too. I think thats the retirement team number, but you can do that in NZA.
quick note: i think if you forget to do this portion, the teams franchise salary numbers get all screwed up because one database thinks theres still a player but another does not.
