When a owner drop the team for any reason they should tell you they are dropping the team and if they don't tell you then and you see know action on the team say for a week or when the draft is over for that  team should be frozen at that time. This way when it come to free agent the player with no contact for pick up and go to another team. The reason why at the end of the draft the team roster is at 60 player and there are other player from other teams with no contact for free agent to pick from. This way someone come in and pick them up they  are not at disadvantage or handicap with a roster of only 30 player on that roster and free agent is over at that time. And they are trying to full the roster with backup player that to them take the fun out of the game. That way the team that have the money or can't pick it apart to were no one want to pick up that team. So when someone dose pick up the team they have the right to sign anyone of those players to new contact or cut them or trade them to other teams just like a new team as lease they can make that decsion on those player that is my opinion.
